What is the Internet of Things?

Smart home symbol

Does your house have a smart thermostat? Or do you wear a fitness tracker to help you stay physically active? If you do, you are part of the Internet of Things, or IoT. It’s become embedded in our lives, as well as in the way organizations operate.

IoT uses a variety of technologies to connect the digital and physical worlds. Physical objects are embedded with sensors—which can monitor things like temperature or motion, or really any change in environment—and actuators—which receive signals from sensors and then do something in response to those changes. The sensors and actuators communicate via wired (for example, Ethernet) or wireless (for example, WiFi, cellular) networks with computing systems that can monitor or manage the health and actions of connected objects and machines.

The physical objects being monitored don’t have to be manufactured—they can include objects in nature, as well as people and animals. While some organizations might view IoT more expansively, our definition excludes systems in which all the embedded sensors are used just to receive intentional human input, such as smartphone apps, which receive data input primarily through a touchscreen, or other networked computer software, in which the sensors consist of a standard keyboard and mouse.

The constant connectivity that IoT enables, combined with data and analytics, provides new opportunities for companies to innovate products and services, as well as to increase the efficiency of operations. Indeed, IoT has emerged  as one of the most significant trends in the digital transformation of business and the economy since the 2010s.

What are some IoT applications?

Looking at IoT applications, which are sometimes described as use cases, can help ground the discussion about what IoT is. Broadly, IoT applications occur in one of nine settings .

  • Human health. Devices can be attached to or inserted inside the human body, including wearable or ingestible devices that monitor or maintain health and wellness , assist in managing diseases such as diabetes, and more.
  • Home. Homeowners can install devices such as home voice assistants, automated vacuums , or security systems.
  • Retail environments. Devices can be installed in stores , banks, restaurants, and arenas to facilitate self-checkout, extend in-store offers, or help optimize inventory.
  • Offices. IoT applications in offices could entail energy management  or security for buildings.
  • Standardized production environments. In such settings, including manufacturing plants , hospitals, or farms, IoT applications often aim to gain operating efficiencies or optimize equipment use and inventory.
  • Custom production environments. In customized settings like those in mining, construction, or oil and gas exploration and production, IoT applications might be used in predictive maintenance  or health and safety efforts .
  • Vehicles. IoT can help with condition-based maintenance, usage-based design, or presales analytics for cars and trucks , ships, airplanes, and trains.
  • Cities. IoT applications can be used for adaptive traffic control, smart meters, environmental monitoring, or managing resources .
  • Outside. In urban environments or other outdoor settings, such as railroad tracks, autonomous vehicles, or flight navigation, IoT applications could involve real-time routing, connected navigation, or shipment tracking.

Other real-world examples abound . IoT solutions are being used in myriad settings: in refrigerators, to help restaurants optimize their food-compliance processes; in fields, to track livestock; in offices, to track how many and how often meeting rooms are used; and beyond.

Introducing McKinsey Explainers : Direct answers to complex questions

What is the economic impact of iot.

The potential value of IoT is large and growing. By 2030, we estimate it could amount to up to $12.5 trillion globally . That includes the value captured by consumers and customers of IoT products and services.

The potential economic value of IoT differs based on settings and usages, with factory settings and human health applications representing outsize shares of this total. Factory settings could generate $1.4 trillion to $3.3 trillion by 2030, or just over a quarter of the total value potential. IoT economic impact in human health settings could reach around 14 percent of the total estimated value.

Another way of looking at IoT’s value is to explore use-case clusters  (similar uses adapted to different settings). Some of the most common use cases account for a sizable share of IoT’s potential economic value:

  • operations optimization, which is basically making the various day-to-day management of assets and people more efficient (41 percent)
  • health (15 percent)
  • human productivity (15 percent)
  • condition-based maintenance (12 percent)

Other clusters include sales enablement, energy management, autonomous vehicles (the fastest-growing cluster), and safety and security.

What are IoT platforms?

To get value from IoT, it helps to have a platform  to create and manage applications, to run analytics, and to store and secure your data. Essentially, these platforms do a lot of things in the background to make life easier and less expensive for developers, managers, and users—in much the same way as an operating system for a laptop. They handle issues like connecting and extracting data from many different endpoints, which might be in inconvenient locations with spotty connectivity.

If you are trying to choose an IoT platform, you’ll need a good understanding of your company’s IoT strategy. Here are five characteristics to consider when evaluating IoT platforms :

  • Applications environment. Here, you might examine questions like: Can the platform develop, test, and maintain multiple applications? Can it connect easily to the applications your company already uses, for example, for enterprise resource planning?
  • Data management. When weighing this element, it’s helpful to understand if the platform can structure and join multiple unfamiliar data sets, for example.
  • Ownership of cloud infrastructure. Does the infrastructure provider own and operate its own data centers, or which public cloud provider does it use? (See “ What is cloud computing? ” for even more on this topic.)
  • Security. What commercial-grade authentication, encryption, and monitoring capability does the platform have, and are they distinctive?
  • Edge processing and control. Here, you could examine whether the platform can do edge analytics, without first bringing data into the cloud, or whether it can be easily configured to control local assets without human intervention.

What should I know about IoT security?

The billions of IoT devices in use have naturally created new vulnerabilities for companies. As more “things” get connected, the number of ways to attack them mushrooms. Pre-IoT, a large corporate network might have needed to account for 50,000 to 500,000 endpoints being vulnerable to attack, while the IoT may involve a network with millions or tens of millions of these endpoints. Promoting cybersecurity , therefore, is crucial in the IoT era.

It’s important to address customer privacy concerns  vis-à-vis connected devices. But managing IoT cybersecurity  is also about protecting critical equipment, such as pacemakers or entire manufacturing plants—which, if attacked, could put your customers’ health or your company’s total production capability at risk.

Six recommendations or actions could help CEOs and other leaders tackling IoT cybersecurity:

  • understand what IoT security will mean for your industry and business model
  • set clear roles and responsibilities for IoT security in your supply chain
  • hold strategic conversations with regulators and collaborate with other industry players
  • view cybersecurity as a priority for the entire product life cycle, and develop skills to achieve it
  • transform mindsets and skills rigorously
  • create a point-of-contact system for external security researchers and implement a postbreach response plan

What is IIoT?

The Industrial Internet of Things , or IIoT, is among the advanced manufacturing technologies collectively referred to is Industry 4.0 , or the Fourth Industrial Revolution.

What are some benefits of IIoT? It can drastically reduce downtime, open up new business models, and improve customer experience—and it can also make organizations more resilient. In the COVID-19 era, for example, digital management tools and constant connectivity allowed some companies to react to market changes swiftly and efficiently by quickly adjusting production capacity and simultaneously supporting remote operations.

Companies using IIoT for digital transformation in manufacturing can follow seven guideposts to align their business, organization, and technology spheres and help leaders successfully position their organizations to reap the full benefits from IIoT:

  • identify and prioritize use cases
  • focus on plant rollout and enablement
  • Organization
  • keep an eye on change and performance management
  • build capabilities and embrace new ways of working
  • attend to IIoT and data infrastructure, with a focus on core platform design, including IT/OT (information technology/operational technology) cybersecurity
  • choose an IIoT platform given the cloud imperative in manufacturing
  • watch the tech ecosystem

What do I need to know about Internet of Things B2B uses?

Internet of Things B2B solutions account for the majority of economic value created from IoT to date. In B2B settings, for example, marrying IoT and AI can improve the predictive-maintenance capabilities of machines, while also empowering service providers to watch the health of their assets in real time, proactively addressing issues before a bigger breakdown occurs.

B2C applications have grown faster than expected, particularly given the adoption of home-automation solutions. However, through 2030, B2B applications are projected to nonetheless account for 62 to 65 percent of total IoT value .

What dynamics could affect IoT adoption?

When it comes to getting more value from IoT, there are tailwinds as well as headwinds that will affect IoT adoption.

Three factors could accelerate the adoption of and impact from IoT solutions:

  • The perceived value proposition. Customers see value in IoT, and the way it enables digital transformation and sustainability efforts—as evidenced by the $1.6 trillion in economic value generated from IoT solutions in 2020.
  • Technology. Affordable technology, which enables IoT deployments at scale, exists for the vast majority of IoT applications. And progress in hardware can be coupled with developments in analytics, AI, and machine learning, which can enable more granular insights and faster decision making.
  • Networks. These are the backbone of IoT, and higher-performing 4G and 5G networks are now available to more people.

Conversely, a variety of factors could constrain adoption. These include the need for change management (capturing value at scale will require collaboration across functions to encourage new behaviors), interoperability issues, and installation challenges, as well as concerns about cybersecurity  and individual privacy.

If your organization is just getting started, it can be helpful to consider what could accelerate enterprise IoT journeys . An interview with Wienke Giezeman, a serial tech entrepreneur and initiator of The Things Network, offers insight on what can drive action: “We’ve seen this in the industry again and again—you cannot solve IoT problems with money. It’s so tempting to try to solve these problems with cash, but really, it’s the creativity and pushing for simplicity that leads to the solution, which shouldn’t be so complicated.”

Is there value in scaling IoT efforts?

To really see the benefits of IoT, companies must embrace the technology at scale, instead of making one-off efforts. If your organization is adopting IoT, here are seven useful actions for scaling IoT :

  • decide who owns IoT in the organization
  • design for scale from the start
  • don’t dip your toe in the water—deploying multiple use cases can be a forcing mechanism in transforming operating models, workflows, and processes
  • invest in technical talent
  • change the entire organization, not just the IT function
  • push for interoperability
  • proactively shape your environment by building and controlling IoT ecosystems

  • From fitness trackers to smart heating systems, the Internet of Things (IoT) describes the growing network of internet-enabled devices.
  • It's also enabling smart cities and, in future, driverless cars.
  • Along with other emerging technologies such as AI, the IoT is part of the Fourth Industrial Revolution.
  • COVID-19 has accelerated the use of IoT technologies, but questions around governance remain.

From soil moisture sensors being used to optimize farmer's yields, to thermostats and thermometers, the Internet of Things (IoT) is transforming the way we live and work.

Billions of networked 'smart' physical objects around the world, on city streets, in homes and hospitals, are constantly collecting and sharing data across the internet, giving them a level of digital intelligence and autonomy.

Around a quarter of businesses were using IoT technologies in 2019, according to McKinsey, up from 13% in 2014.

And already, there are more connected devices than people in the world, according to the World Economic Forum's State of the Connected World report, and it is predicted that by 2025, 41.6 billion devices will be capturing data on how we live, work, move through our cities and operate and maintain the machines on which we depend.

The digital transformation that is taking place due to emerging technologies, including robotics, the IoT and artificial intelligence, is known as the Fourth Industrial Revolution - and COVID-19 has accelerated the use of these technologies.

IoT connections growth rate.

The World Economic Forum was the first to draw the world’s attention to the Fourth Industrial Revolution, the current period of unprecedented change driven by rapid technological advances. Policies, norms and regulations have not been able to keep up with the pace of innovation, creating a growing need to fill this gap.

The Forum established the Centre for the Fourth Industrial Revolution Network in 2017 to ensure that new and emerging technologies will help—not harm—humanity in the future. Headquartered in San Francisco, the network launched centres in China, India and Japan in 2018 and is rapidly establishing locally-run Affiliate Centres in many countries around the world.

The global network is working closely with partners from government, business, academia and civil society to co-design and pilot agile frameworks for governing new and emerging technologies, including artificial intelligence (AI) , autonomous vehicles , blockchain , data policy , digital trade , drones , internet of things (IoT) , precision medicine and environmental innovations .

A brief history of the IoT

The concept of adding sensors and intelligence to physical objects was first discussed in the 1980s, when some university students decided to modify a Coca-Cola vending machine to track its contents remotely. But the technology was bulky and progress was limited.

The term ‘Internet of Things’ was coined in 1999 by the computer scientist Kevin Ashton. While working at Procter & Gamble, Ashton proposed putting radio-frequency identification (RFID) chips on products to track them through a supply chain.

He reportedly worked the then-buzzword ‘internet’ into his proposal to get the executives’ attention. And the phrase stuck.

Over the next decade, public interest in IoT technology began to take off, as more and more connected devices came to market.

In 2000, LG announced the first smart refrigerator, in 2007 the first iPhone was launched and by 2008, the number of connected devices exceeded the number of people on the planet.

In 2009, Google started testing driverless cars and in 2011, Google's Nest smart thermostat hit the market, which allowed remote control of central heating.

Everyday uses

Connected devices fall into three domains: consumer IoT, such as wearables, enterprise IoT, which includes smart factories and precision agriculture, and public spaces IoT, such as waste management.

Businesses use IoT to optimize their supply chains, manage inventory and improve customer experience, while smart consumer devices such as the Amazon Echo speaker, are now ubiquitous in homes due to the prevalence of low-cost and low-power sensors.

Cities have been deploying IoT technology for more than a decade - to streamline everything from water meter readings to traffic flow.

"In New York City, for example, every single building (so more than 817,000) was retrofitted with a wireless water meter, starting back in 2008, which replaced the manual system where you had to walk up to a meter read the numbers and generate bills that way," says Jeff Merritt, the World Economic Forum's head of IoT and Urban Transformation.

"Many cities now leverage license plate readers, traffic counters, red light cameras, radiation sensors and surveillance cameras to manage day-to-day operations."

a diagram of the Internet of Things

In medicine, the IoT can help improve healthcare through real-time remote patient monitoring, robotic surgery and devices such as smart inhalers.

In the past 12 months, the role of the IoT in the COVID-19 pandemic has been invaluable.

"IoT applications such as connected thermal cameras, contact tracing devices and health-monitoring wearables are providing critical data needed to help fight the disease, while temperature sensors and parcel tracking will help ensure that sensitive COVID-19 vaccines are distributed safely," according to the Forum's State of the Connected World report.

Beyond healthcare, IoT has helped make COVID disrupted supply chains more resilient, automated activities in warehouses and on factory floors to help promote social distancing and provided safe remote access to industrial machines.

The future of IoT

The range of potential IoT applications is " limited only by the human imagination " - and many of these applications can benefit the planet, as well as its people.

A 2018 analysis of more than 640 IoT deployments, led by the World Economic Forum in collaboration with research firm IoT Analytics, showed that 84% of existing IoT deployments address, or have the power to advance, the UN's Sustainable Development Goals.

These include promoting more efficient use of natural resources, building better, fairer “smart cities”, and developing clean, affordable energy alternatives.

IoT smart roads that connect with self-driving cars could improve driver safety and optimize traffic flow, potentially reducing the average commute time by 30 minutes . Emergency responder times could also be cut significantly.

Real-time crime mapping and predictive policing tools could also help prevent crime. McKinsey estimates that using data to deploy scarce resources more effectively could save 300 lives a year in a city with the population and profile of Rio de Janeiro.

Weighing the risks

But for all the benefits, IoT technologies can also be misused and risks include security and privacy issues, cybercrime, surveillance at work, home or in public spaces and control of mobility and expression.

Key differences between IoT and traditional digital systems in safety and security.

The Forum's State of the Connected World report identifies a 'governance gap' that needs to be closed between the potential risks and society’s efforts to safeguard against them through laws, industry standards and self-governance approaches.

"Effective technology governance mitigates risks and reduces the potential harms to society while also helping to maximize the technology’s positive impacts."

Industry leaders will come together from April 6-7 for the World Economic Forum's Global Technology Governance Summit , which is dedicated to ensuring the responsible design and deployment of emerging technologies through public-private collaboration.

Internet of Things (IoT) is a new paradigm that has changed the traditional way of living into a high tech life style. Smart city, smart homes, pollution control, energy saving, smart transportation, smart industries are such transformations due to IoT. A lot of crucial research studies and investigations have been done in order to enhance the technology through IoT. However, there are still a lot of challenges and issues that need to be addressed to achieve the full potential of IoT. These challenges and issues must be considered from various aspects of IoT such as applications, challenges, enabling technologies, social and environmental impacts etc. The main goal of this review article is to provide a detailed discussion from both technological and social perspective. The article discusses different challenges and key issues of IoT, architecture and important application domains. Also, the article bring into light the existing literature and illustrated their contribution in different aspects of IoT. Moreover, the importance of big data and its analysis with respect to IoT has been discussed. This article would help the readers and researcher to understand the IoT and its applicability to the real world.

Introduction

The Internet of Things (IoT) is an emerging paradigm that enables the communication between electronic devices and sensors through the internet in order to facilitate our lives. IoT use smart devices and internet to provide innovative solutions to various challenges and issues related to various business, governmental and public/private industries across the world [ 1 ]. IoT is progressively becoming an important aspect of our life that can be sensed everywhere around us. In whole, IoT is an innovation that puts together extensive variety of smart systems, frameworks and intelligent devices and sensors (Fig.  1 ). Moreover, it takes advantage of quantum and nanotechnology in terms of storage, sensing and processing speed which were not conceivable beforehand [ 2 ]. Extensive research studies have been done and available in terms of scientific articles, press reports both on internet and in the form of printed materials to illustrate the potential effectiveness and applicability of IoT transformations. It could be utilized as a preparatory work before making novel innovative business plans while considering the security, assurance and interoperability.

General architecture of IoT

A great transformation can be observed in our daily routine life along with the increasing involvement of IoT devices and technology. One such development of IoT is the concept of Smart Home Systems (SHS) and appliances that consist of internet based devices, automation system for homes and reliable energy management system [ 3 ]. Besides, another important achievement of IoT is Smart Health Sensing system (SHSS). SHSS incorporates small intelligent equipment and devices to support the health of the human being. These devices can be used both indoors and outdoors to check and monitor the different health issues and fitness level or the amount of calories burned in the fitness center etc. Also, it is being used to monitor the critical health conditions in the hospitals and trauma centers as well. Hence, it has changed the entire scenario of the medical domain by facilitating it with high technology and smart devices [ 4 , 5 ]. Moreover, IoT developers and researchers are actively involved to uplift the life style of the disabled and senior age group people. IoT has shown a drastic performance in this area and has provided a new direction for the normal life of such people. As these devices and equipment are very cost effective in terms of development cost and easily available within a normal price range, hence most of the people are availing them [ 6 ]. Thanks to IoT, as they can live a normal life. Another important aspect of our life is transportation. IoT has brought up some new advancements to make it more efficient, comfortable and reliable. Intelligent sensors, drone devices are now controlling the traffic at different signalized intersections across major cities. In addition, vehicles are being launched in markets with pre-installed sensing devices that are able to sense the upcoming heavy traffic congestions on the map and may suggest you another route with low traffic congestion [ 7 ]. Therefore IoT has a lot to serve in various aspects of life and technology. We may conclude that IoT has a lot of scope both in terms of technology enhancement and facilitate the humankind.

IoT has also shown its importance and potential in the economic and industrial growth of a developing region. Also, in trade and stock exchange market, it is being considered as a revolutionary step. However, security of data and information is an important concern and highly desirable, which is a major challenging issue to deal with [ 5 ]. Internet being a largest source of security threats and cyber-attacks has opened the various doors for hackers and thus made the data and information insecure. However, IoT is committed to provide the best possible solutions to deal with security issues of data and information. Hence, the most important concern of IoT in trade and economy is security. Therefore, the development of a secure path for collaboration between social networks and privacy concerns is a hot topic in IoT and IoT developers are working hard for this.

The remaining part of the article is organized as follows: “ Literature survey ” section will provide state of art on important studies that addressed various challenges and issues in IoT. “ IoT architecture and technologies ” section discussed the IoT functional blocks, architecture in detail. In “ Major key issues and challenges of IoT ” section, important key issues and challenges of IoT is discussed. “ Major IoT applications ” section provides emerging application domains of IoT. In “ Importance of big data analytics in IoT ” section, the role and importance of big data and its analysis is discussed. Finally, the article concluded in “ Conclusions ” section.

Literature survey

IoT has a multidisciplinary vision to provide its benefit to several domains such as environmental, industrial, public/private, medical, transportation etc. Different researchers have explained the IoT differently with respect to specific interests and aspects. The potential and power of IoT can be seen in several application domains. Figure  2 illustrates few of the application domains of IoTs potentials.

Some of the potential application domains of IoT

Various important IoT projects have taken charge over the market in last few years. Some of the important IoT projects that have captured most of the market are shown in Fig.  3 . In Fig.  3 , a global distribution of these IoT projects is shown among American, European and Asia/Pacific region. It can be seen that American continent are contributing more in the health care and smart supply chain projects whereas contribution of European continent is more in the smart city projects [ 8 ].

Smart city is one of the trendy application areas of IoT that incorporates smart homes as well. Smart home consists of IoT enabled home appliances, air-conditioning/heating system, television, audio/video streaming devices, and security systems which are communicating with each other in order to provide best comfort, security and reduced energy consumption. All this communication takes place through IoT based central control unit using Internet. The concept of smart city gained popularity in the last decade and attracted a lot of research activities [ 9 ]. The smart home business economy is about to cross the 100 billion dollars by 2022 [ 10 ]. Smart home does not only provide the in-house comfort but also benefits the house owner in cost cutting in several aspects i.e. low energy consumption will results in comparatively lower electricity bill. Besides smart homes, another category that comes within smart city is smart vehicles. Modern cars are equipped with intelligent devices and sensors that control most of the components from the headlights of the car to the engine [ 11 ]. The IoT is committed towards developing a new smart car systems that incorporates wireless communication between car-to-car and car-to-driver to ensure predictive maintenance with comfortable and safe driving experience [ 12 ].

Khajenasiri et al. [ 10 ] performed a survey on the IoT solutions for smart energy control to benefit the smart city applications. They stated that at present IoT has been deployed in very few application areas to serve the technology and people. The scope of IoT is very wide and in near future IoT is able to capture almost all application areas. They mentioned that energy saving is one of the important part of the society and IoT can assist in developing a smart energy control system that will save both energy and money. They described an IoT architecture with respect to smart city concept. The authors also discussed that one of the challenging task in achieving this is the immaturity of IoT hardware and software. They suggested that these issues must be resolved to ensure a reliable, efficient and user friendly IoT system.

Alavi et al. [ 13 ] addressed the urbanization issue in the cities. The movement of people from rural to urban atmosphere resulting in growing population of the cities. Therefore, there is a need to provide smart solutions for mobility, energy, healthcare and infrastructure. Smart city is one of the important application areas for IoT developers. It explores several issues such as traffic management, air quality management, public safety solutions, smart parking, smart lightning and smart waste collection (Fig.  5 ). They mentioned that IoT is working hard to tackle these challenging issues. The need for improved smart city infrastructure with growing urbanization has opened the doors for entrepreneurs in the field of smart city technologies. The authors concluded that IoT enabled technology is very important for the development of sustainable smart cities.

Potential IoT application areas for smart cities

Another important issue of IoT that requires attention and a lot of research is security and privacy. Weber [ 14 ] focused on these issues and suggested that a private organization availing IoT must incorporate data authentication, access control, resilience to attacks and client privacy into their business activities that would be an additional advantage. Weber suggested that in order to define global security and privacy issues, IoT developers must take into account the geographical limitations of the different countries. A generic framework needs to be designed to fit the global needs in terms of privacy and security. It is highly recommended to investigate and recognize the issues and challenges in privacy and security before developing the full fledge working IoT framework.

Later, Heer et al. [ 15 ] came up with a security issue in IP based IoT system. They mentioned that internet is backbone for the communication among devices that takes place in an IoT system. Therefore, security issues in IP based IoT systems are an important concern. In addition, security architecture should be designed considering the life cycle and capabilities of any object in the IoT system. It also includes the involvement of the trusted third party and the security protocols. The security architecture with scalability potential to serve the small-scale to large-scale things in IoT is highly desirable. The study pointed out that IoT gave rise to a new way of communication among several things across the network therefore traditional end to end internet protocol are not able to provide required support to this communication. Therefore, new protocols must be designed considering the translations at the gateways to ensure end-to-end security. Moreover, all the layers responsible for communication has their own security issues and requirements. Therefore, satisfying the requirements for one particular layers will leave the system into a vulnerable state and security should be ensured for all the layers.

Authentication and access control is another issue in IoT that needs promising solutions to strengthen the security. Liu et al. [ 16 ] brought up a solution to handle authentication and access control. Authentication is very important to verify the communicating parties to prevent the loss of confidential information. Liu et al. [ 16 ] provided an authentication scheme based on Elliptic Curve Cryptosystem and verified it on different security threats i.e. eavesdropping, man-in-the-middle attack, key control and replay attack. They claimed that there proposed schemes are able to provide better authentication and access control in IoT based communication. Later, Kothmayr et al. [ 17 ] proposed a two-way authentication scheme based of datagram transport layer security (DTLS) for IoT. The attackers over the internet are always active to steal the secured information. The proposed approach are able to provide message security, integrity, authenticity and confidentiality, memory overhead and end-to-end latency in the IoT based communication network.

Li et al. [ 18 ] proposed a dynamic approach for data centric IoT applications with respect to cloud platforms. The need of an appropriate device, software configuration and infrastructure requires efficient solutions to support massive amount of IoT applications that are running on cloud platforms. IoT developers and researchers are actively engaged in developing solutions considering both massive platforms and heterogeneous nature of IoT objects and devices. Olivier et al. [ 19 ] explained the concept of software defined networking (SDN) based architecture that performs well even if a well-defined architecture is not available. They proposed that SDN based security architecture is more flexible and efficient for IoT.

Luk et al. [ 20 ] stated that the main task of a secure sensor network (SSN) is to provide data privacy, protection from replay attacks and authentication. They discussed two popular SSN services namely TinySec [ 21 ] and ZigBee [ 22 ]. They mentioned that although both the SSN services are efficient and reliable, however, ZigBee is comparatively provides higher security but consumes high energy whereas TinySec consumes low energy but not as highly secured as ZigBee. They proposed another architecture MiniSec to support high security and low energy consumption and demonstrated its performance for the Telos platform. Yan et al. [ 23 ] stated that trust management is an important issue in IoT. Trust management helps people to understand and trust IoT services and applications without worrying about uncertainty issues and risks [ 24 ]. They investigated different issues in trust management and discussed its importance with respect to IoT developers and users.

Noura et al. [ 25 ] stated the importance of interoperability in IoT as it allows integration of devices, services from different heterogeneous platforms to provide the efficient and reliable service. Several other studies focused on the importance of interoperability and discussed several challenges that interoperability issue is facing in IoT [ 26 , 27 , 28 ]. Kim et al. [ 29 ] addressed the issue of climate change and proposed an IoT based ecological monitoring system. They mentioned that existing approaches are time consuming and required a lot of human intervention. Also, a routine visit is required to collect the information from the sensors installed at the site under investigation. Also, some information remained missing which leads to not highly accurate analysis. Therefore, IoT based framework is able to solve this problem and can provide high accuracy in analysis and prediction. Later, Wang et al. [ 30 ] shows their concern for domestic waste water treatment. They discussed several deficiencies in the process of waste water treatment and dynamic monitoring system and suggested effective solutions based on IoT. They stated that IoT can be very effective in the waste water treatment and process monitoring.

Agriculture is one of the important domain around the world. Agriculture depends on several factors i.e. geographical, ecological etc. Qiu et al. [ 31 ] stated that technology that is being used for ecosystem control is immature with low intelligence level. They mentioned that it could be a good application area for IoT developers and researchers.

Qiu et al. [ 31 ] proposed an intelligent monitoring platform framework for facility agriculture ecosystem based on IoT that consists of four layer mechanism to manage the agriculture ecosystem. Each layer is responsible for specific task and together the framework is able to achieve a better ecosystem with reduced human intervention.

Another important concern around the world is climate change due to global warming. Fang et al. [ 32 ] introduced an integrated information system (IIS) that integrates IoT, geo-informatics, cloud computing, global positioning system (GPS), geographical information system (GIS) and e-science in order to provide an effective environmental monitoring and control system. They mentioned that the proposed IIS provides improved data collection, analysis and decision making for climate control. Air pollution is another important concern worldwide. Various tools and techniques are available to air quality measures and control. Cheng et al. [ 33 ] proposed AirCloud which is a cloud based air quality and monitoring system. They deployed AirCloud and evaluated its performance using 5 months data for the continuous duration of 2 months.

Temglit et al. [ 34 ] considered Quality of Service (QoS) as an important challenge and a complex task in evaluation and selection of IoT devices, protocols and services. QoS is very important criteria to attract and gain trust of users towards IoT services and devices. They came up with an interesting distributed QoS selection approach. This approach was based on distributed constraint optimization problem and multi-agent paradigm. Further, the approach was evaluated based on several experiments under realistic distributed environments. Another important aspect of IoT is its applicability to the environmental and agriculture standards. Talavera et al. [ 35 ] focused in this direction and presented the fundamental efforts of IoT for agro-industrial and environmental aspects in a survey study. They mentioned that the efforts of IoT in these areas are noticeable. IoT is strengthening the current technology and benefiting the farmers and society. Jara et al. [ 36 ] discussed the importance of IoT based monitoring of patients health. They suggested that IoT devices and sensors with the help of internet can assist health monitoring of patients. They also proposed a framework and protocol to achieve their objective. Table 1 provides a summary of the important studies and the direction of research with a comparison of studies on certain evaluation parameters.

IoT architecture and technologies

The IoT architecture consists of five important layers that defines all the functionalities of IoT systems. These layers are perception layer, network layer, middleware layer, application layer, business layer. At the bottom of IoT architecture, perception layer exists that consists of physical devices i.e. sensors, RFID chips, barcodes etc. and other physical objects connected in IoT network. These devices collects information in order to deliver it to the network layer. Network layer works as a transmission medium to deliver the information from perception layer to the information processing system. This transmission of information may use any wired/wireless medium along with 3G/4G, Wi-Fi, Bluetooth etc. Next level layer is known as middleware layer. The main task of this layer is to process the information received from the network layer and make decisions based on the results achieved from ubiquitous computing. Next, this processed information is used by application layer for global device management. On the top of the architecture, there is a business layer which control the overall IoT system, its applications and services. The business layer visualizes the information and statistics received from the application layer and further used this knowledge to plan future targets and strategies. Furthermore, the IoT architectures can be modified according to the need and application domain [ 19 , 20 , 37 ]. Besides layered framework, IoT system consists of several functional blocks that supports various IoT activities such as sensing mechanism, authentication and identification, control and management [ 38 ]. Figure  6 illustrates such functional blocks of IoT architecture.

figure 6

A generic function module of IoT system

There are several important functional blocks responsible for I/O operations, connectivity issues, processing, audio/video monitoring and storage management. All these functional block together incorporates an efficient IoT system which are important for optimum performance. Although, there are several reference architectures proposed with the technical specifications, but these are still far from the standard architecture that is suitable for global IoT [ 39 ]. Therefore, a suitable architecture is still needsvk to be designed that could satisfy the global IoT needs. The generic working structure of IoT system is shown in Fig.  7 . Figure  7 shows a dependency of IoT on particular application parameters. IoT gateways have an important role in IoT communication as it allows connectivity between IoT servers and IoT devices related to several applications [ 40 ].

figure 7

Working structure of IoT

Scalability, modularity, interoperability and openness are the key design issues for an efficient IoT architecture in a heterogenous environment. The IoT architecture must be designed with an objective to fulfil the requirements of cross domain interactions, multi-system integration with the potential of simple and scalable management functionalities, big data analytics and storage, and user friendly applications. Also, the architecture should be able to scaleup the functionality and add some intelligence and automation among the IoT devices in the system.

Moreover, increasing amount of massive data being generated through the communication between IoT sensors and devices is a new challenge. Therefore, an efficient architecture is required to deal with massive amount of streaming data in IoT system. Two popular IoT system architectures are cloud and fog/edge computing that supports with the handling, monitoring and analysis of huge amount of data in IoT systems. Therefore, a modern IoT architecture can be defined as a 4 stage architecture as shown in Fig.  8 .

figure 8

Four stage IoT architecture to deal with massive data

In stage 1 of the architecture, sensors and actuators plays an important role. Real world is comprised of environment, humans, animals, electronic gadgets, smart vehicles, and buildings etc. Sensors detect the signals and data flow from these real world entities and transforms into data which could further be used for analysis. Moreover, actuators is able to intervene the reality i.e. to control the temperature of the room, to slow down the vehicle speed, to turn off the music and light etc. Therefore, stage 1 assist in collecting data from real world which could be useful for further analysis. Stage 2 is responsible to collaborate with sensors and actuators along with gateways and data acquisition systems. In this stage, massive amount of data generated in stage 1 is aggregated and optimized in a structured way suitable for processing. Once the massive amount of data is aggregated and structured then it is ready to be passed to stage 3 which is edge computing. Edge computing can be defined as an open architecture in distributed fashion which allows use of IoT technologies and massive computing power from different locations worldwide. It is very powerful approach for streaming data processing and thus suitable for IoT systems. In stage 3, edge computing technologies deals with massive amount of data and provides various functionalities such as visualization, integration of data from other sources, analysis using machine learning methods etc. The last stage comprises of several important activities such as in depth processing and analysis, sending feedback to improve the precision and accuracy of the entire system. Everything at this stage will be performed on cloud server or data centre. Big data framework such as Hadoop and Spark may be utilized to handle this large streaming data and machine learning approaches can be used to develop better prediction models which could help in a more accurate and reliable IoT system to meet the demand of present time.

Major key issues and challenges of IoT

The involvement of IoT based systems in all aspects of human lives and various technologies involved in data transfer between embedded devices made it complex and gave rise to several issues and challenges. These issues are also a challenge for the IoT developers in the advanced smart tech society. As technology is growing, challenges and need for advanced IoT system is also growing. Therefore, IoT developers need to think of new issues arising and should provide solutions for them.

Security and privacy issues

One of the most important and challenging issues in the IoT is the security and privacy due to several threats, cyber attacks, risks and vulnerabilities [ 41 ]. The issues that give rise to device level privacy are insufficient authorization and authentication, insecure software, firmware, web interface and poor transport layer encryption [ 42 ]. Security and privacy issues are very important parameters to develop confidence in IoT Systems with respect to various aspects [ 43 ]. Security mechanisms must be embedded at every layer of IoT architecture to prevent security threats and attacks [ 23 ]. Several protocols are developed and efficiently deployed on every layer of communication channel to ensure the security and privacy in IoT based systems [ 44 , 45 ]. Secure Socket Layer (SSL) and Datagram Transport Layer Security (DTLS) are one of the cryptographic protocols that are implemented between transport and application layer to provide security solutions in various IoT systems [ 44 ]. However, some IoT applications require different methods to ensure the security in communication between IoT devices. Besides this, if communication takes place using wireless technologies within the IoT system, it becomes more vulnerable to security risks. Therefore, certain methods should be deployed to detect malicious actions and for self healing or recovery. Privacy on the other hand is another important concern which allows users to feel secure and comfortable while using IoT solutions. Therefore, it is required to maintain the authorization and authentication over a secure network to establish the communication between trusted parties [ 46 ]. Another issue is the different privacy policies for different objects communicating within the IoT system. Therefore, each object should be able to verify the privacy policies of other objects in IoT system before transmitting the data.

Interoperability/standard issues

Interoperability is the feasibility to exchange the information among different IoT devices and systems. This exchange of information does not rely on the deployed software and hardware. The interoperability issue arises due to the heterogeneous nature of different technology and solutions used for IoT development. The four interoperability levels are technical, semantic, syntactic and organizational [ 47 ]. Various functionalities are being provided by IoT systems to improve the interoperability that ensures communication between different objects in a heterogeneous environment. Additionally, it is possible to merge different IoT platforms based on their functionalities to provide various solutions for IoT users [ 48 ]. Considering interoperability an important issue, researchers approved several solutions that are also know as interoperability handling approaches [ 49 ]. These solutions could be adapaters/gateways based, virtual networks/overlay based, service oriented architecture based etc. Although interoperability handling approaches ease some pressure on IoT systems but there are still certain challenges remain with interoperability that could be a scope for future studies [ 25 ].

Ethics, law and regulatory rights

Another issue for IoT developers is the ethics, law and regulatory rights. There are certain rules and regulations to maintain the standard, moral values and to prevent the people from violating them. Ethics and law are very similar term with the only difference is that ethics are standards that people believes and laws are certain restrictions decided by the government. However, both ethics and laws are designed to maintain the standard, quality and prevent people from illegal use. With the development of IoT, several real life problems are solved but it has also given rise to critical ethical and legal challenges [ 50 ]. Data security, privacy protection, trust and safety, data usability are some of those challenges. It has also been observed that majority of IoT users are supporting government norms and regulations with respect to data protection, privacy and safety due to the lack of trust in IoT devices. Therefore, this issue must be taken into consideration to maintain and improve the trust among people for the use of IoT devices and systems.

Scalability, availability and reliability

A system is scalable if it is possible to add new services, equipments and devices without degrading its performance. The main issue with IoT is to support a large number of devices with different memory, processing, storage power and bandwidth [ 28 ]. Another important issue that must be taken into consideration is the availability. Scalability and availability both should be deployed together in the layered framework of IoT. A great example of scalability is cloud based IoT systems which provide sufficient support to scale the IoT network by adding up new devices, storage and processing power as required.

However, this global distributed IoT network gives rise to a new research paradigm to develop a smooth IoT framework that satisfy global needs [ 51 ]. Another key challenge is the availability of resources to the authentic objects regardless of their location and time of the requirement. In a distributed fashion, several small IoT networks are timely attached to the global IoT platforms to utilize their resources and services. Therefore, availability is an important concern [ 52 ]. Due to the use of different data transmission channels i.e. satellite communication, some services and availability of resources may be interrupted. Therefore, an independent and reliable data transmission channel is required for uninterrupted availability of resources and services.

Quality of Service (QoS)

Quality of Service (QoS) is another important factor for IoT. QoS can be defined as a measure to evaluate the quality, efficiency and performance of IoT devices, systems and architecture [ 34 ]. The important and required QoS metrics for IoT applications are reliability, cost, energy consumption, security, availability and service time [ 53 ]. A smarter IoT ecosystem must fulfill the requirements of QoS standards. Also, to ensure the reliability of any IoT service and device, its QoS metrics must be defined first. Further, users may also be able to specifiy their needs and requirements accordingly. Several approaches can be deployed for QoS assessment, however as mentioned by White et al. [ 54 ] there is a trade-off between quality factors and approaches. Therefore, good quality models must be deployed to overcome this trade-off. There are certain good quality models available in literature such as ISO/IEC25010 [ 55 ] and OASIS-WSQM [ 56 ] which can be used to evaluate the approaches used for QoS assessment. These models provides a wide range of quality factors that is quite sufficient for QoS assessment for IoT services. Table  2 summarizes the different studies with respect to IoT key challenges and issues discussed above.

Major IoT applications

Emerging economy, environmental and health-care.

IoT is completely devoted to provide emerging public and financial benefits and development to the society and people. This includes a wide range of public facilities i.e. economic development, water quality maintenance, well-being, industrialization etc. Overall, IoT is working hard to accomplish the social, health and economic goals of United Nations advancement step. Environmental sustainability is another important concern. IoT developers must be concerned about environmental impact of the IoT systems and devices to overcome the negative impact [ 48 ]. Energy consumption by IoT devices is one of the challenges related to environmental impact. Energy consumption is increasing at a high rate due to internet enabled services and edge cutting devices. This area needs research for the development of high quality materials in order to create new IoT devices with lower energy consumption rate. Also, green technologies can be adopted to create efficient energy efficient devices for future use. It is not only environmental friendly but also advantageous for human health. Researchers and engineers are engaged in developing highly efficient IoT devices to monitor several health issues such as diabetes, obesity or depression [ 57 ]. Several issues related to environment, energy and healthcare are considered by several studies.

Smart city, transport and vehicles

IoT is transforming the traditional civil structure of the society into high tech structure with the concept of smart city, smart home and smart vehicles and transport. Rapid improvements are being done with the help of supporting technologies such as machine learning, natural language processing to understand the need and use of technology at home [ 58 ]. Various technologies such as cloud server technology, wireless sensor networks that must be used with IoT servers to provide an efficient smart city. Another important issue is to think about environmental aspect of smart city. Therefore, energy efficient technologies and Green technologies should also be considered for the design and planning of smart city infrastructure. Further, smart devices which are being incorporated into newly launched vehicles are able to detect traffic congestions on the road and thus can suggest an optimum alternate route to the driver. This can help to lower down the congestion in the city. Furthermore, smart devices with optimum cost should be designed to be incorporated in all range vehicles to monitor the activity of engine. IoT is also very effective in maintaining the vehicle’s health. Self driving cars have the potential to communicate with other self driving vehicles by the means of intelligent sensors. This would make the traffic flow smoother than human-driven cars who used to drive in a stop and go manner. This procedure will take time to be implemented all over the world. Till the time, IoT devices can help by sensing traffic congestion ahead and can take appropriate actions. Therefore, a transport manufacturing company should incorporate IoT devices into their manufactured vehicles to provide its advantage to the society.

Agriculture and industry automation

The world’s growing population is estimated to reach approximate 10 billion by 2050. Agriculture plays an important role in our lives. In order to feed such a massive population, we need to advance the current agriculture approaches. Therefore, there is a need to combine agriculture with technology so that the production can be improved in an efficient way. Greenhouse technology is one of the possible approaches in this direction. It provides a way to control the environmental parameters in order to improve the production. However, manual control of this technology is less effective, need manual efforts and cost, and results in energy loss and less production. With the advancement of IoT, smart devices and sensors makes it easier to control the climate inside the chamber and monitor the process which results in energy saving and improved production (Fig.  9 ). Automatization of industries is another advantage of IoT. IoT has been providing game changing solutions for factory digitalization, inventory management, quality control, logistics and supply chain optimization and management.

Importance of big data analytics in IoT

An IoT system comprises of a huge number of devices and sensors that communicates with each other. With the extensive growth and expansion of IoT network, the number of these sensors and devices are increasing rapidly. These devices communicate with each other and transfer a massive amount of data over internet. This data is very huge and streaming every second and thus qualified to be called as big data. Continuous expansion of IoT based networks gives rise to complex issue such as management and collection of data, storage and processing and analytics. IoT big data framework for smart buildings is very useful to deal with several issues of smart buildings such as managing oxygen level, to measure the smoke/hazardous gases and luminosity [ 59 ]. Such framework is capable to collect the data from the sensors installed in the buildings and performs data analytics for decision making. Moreover, industrial production can be improved using an IoT based cyber physical system that is equipped with an information analysis and knowledge acquisition techniques [ 60 ]. Traffic congestion is an important issue with smart cities. The real time traffic information can be collected through IoT devices and sensors installed in traffic signals and this information can be analyzed in an IoT based traffic management system [ 61 ]. In healthcare analysis, the IoT sensors used with patients generate a lot of information about the health condition of patients every second. This large amount of information needs to be integrated at one database and must be processed in real time to take quick decision with high accuracy and big data technology is the best solution for this job [ 62 ]. IoT along with big data analytics can also help to transform the traditional approaches used in manufacturing industries into the modern one [ 63 ]. The sensing devices generates information which can be analyzed using big data approaches and may help in various decision making tasks. Furthermore, use of cloud computing and analytics can benefit the energy development and conservation with reduced cost and customer satisfaction [ 64 ]. IoT devices generate a huge amount of streaming data which needs to be stored effectively and needs further analysis for decision making in real time. Deep learning is very effective to deal with such a large information and can provide results with high accuracy [ 65 ]. Therefore, IoT, Big data analytics and Deep learning together is very important to develop a high tech society.

Conclusions

Recent advancements in IoT have drawn attention of researchers and developers worldwide. IoT developers and researchers are working together to extend the technology on large scale and to benefit the society to the highest possible level. However, improvements are possible only if we consider the various issues and shortcomings in the present technical approaches. In this survey article, we presented several issues and challenges that IoT developer must take into account to develop an improved model. Also, important application areas of IoT is also discussed where IoT developers and researchers are engaged. As IoT is not only providing services but also generates a huge amount of data. Hence, the importance of big data analytics is also discussed which can provide accurate decisions that could be utilized to develop an improved IoT system.

Introduction to Internet of Things (IoT) – Set 1

IoT stands for Internet of Things. It refers to the interconnectedness of physical devices, such as appliances and vehicles, that are embedded with software, sensors, and connectivity which enables these objects to connect and exchange data. This technology allows for the collection and sharing of data from a vast network of devices, creating opportunities for more efficient and automated systems.

Internet of Things (IoT) is the networking of physical objects that contain electronics embedded within their architecture in order to communicate and sense interactions amongst each other or with respect to the external environment. In the upcoming years, IoT-based technology will offer advanced levels of services and practically change the way people lead their daily lives. Advancements in medicine, power, gene therapies, agriculture, smart cities, and smart homes are just a few of the categorical examples where IoT is strongly established. 

IOT is a system of interrelated things, computing devices, mechanical and digital machines, objects, animals, or people that are provided with unique identifiers. And the ability to transfer the data over a network requiring human-to-human or human-to-computer interaction.

History of IOT

  • 1982- Vending machine
  • 1990-Toaster
  • 1999-IOT(Kevin Ashton)
  • 2000-LG Smart Fridge
  • 2004-Smart Watch
  • 2007-Smart i phone
  • 2009-Car Testing
  • 2011-Smart TV
  • 2013-Google Lens
  • 2015-Tesla autopilot

Four Key Components of IOT

  • Device or sensor
  • Connectivity
  • Data processing

IoT is network of interconnected computing devices which are embedded in everyday objects, enabling them to send and receive data.

Over 9 billion ‘Things’ (physical objects) are currently connected to the Internet, as of now. In the near future, this number is expected to rise to a whopping 20 billion. 

Main Components Used in IoT

  • Low-power embedded systems: Less battery consumption, high performance are the inverse factors that play a significant role during the design of electronic systems. 
  • Sensors: Sensors are the major part of any IoT application. It is a physical device that measures and detects certain physical quantities and converts it into signal which can be provided as an input to processing or control unit for analysis purpose.

Different types of Sensors

  • Temperature Sensors
  • Image Sensors
  • Gyro Sensors
  • Obstacle Sensors
  • MQ-02/05 Gas Sensor
  • Ultrasonic Distance Sensor
  • Control Units: It is a unit of small computer on a single integrated circuit containing microprocessor or processing core, memory and programmable input/output devices/peripherals. It is responsible for major processing work of IoT devices and all logical operations are carried out here.
  • Cloud computing: Data collected through IoT devices is massive, and this data has to be stored on a reliable storage server. This is where cloud computing comes into play. The data is processed and learned, giving more room for us to discover where things like electrical faults/errors are within the system. 
  • Availability of big data: We know that IoT relies heavily on sensors, especially in real-time. As these electronic devices spread throughout every field, their usage is going to trigger a massive flux of big data. 
  • Networking connection: In order to communicate, internet connectivity is a must, where each physical object is represented by an IP address. However, there are only a limited number of addresses available according to the IP naming. Due to the growing number of devices, this naming system will not be feasible anymore. Therefore, researchers are looking for another alternative naming system to represent each physical object.

Ways of Building IOT

There are two ways of building IoT:

  • Form a separate internet work including only physical objects. 
  • Make the Internet ever more expansive, but this requires hard-core technologies such as rigorous cloud computing and rapid big data storage (expensive).

In the near future, IoT will become broader and more complex in terms of scope. It will change the world in terms of 

“anytime, anyplace, anything in connectivity.”

IoT Enablers

  • RFIDs: uses radio waves in order to electronically track the tags attached to each physical object.
  • Sensors: devices that are able to detect changes in an environment (ex: motion detectors).
  • Nanotechnology: as the name suggests, these are tiny devices with dimensions usually less than a hundred nanometers.
  • Smart networks: (ex: mesh topology). 

Working with IoT Devices

  • Collect and Transmit Data : For this purpose sensors are widely used they are used as per requirements in different application areas.
  • Actuate device based on triggers produced by sensors or processing devices: If certain conditions are satisfied or according to user’s requirements if certain trigger is activated then which action to perform that is shown by Actuator devices. 
  • Receive Information: From network devices, users or devices can take certain information also for their analysis and processing purposes .
  • Communication Assistance: Communication assistance is the phenomenon of communication between 2 networks or communication between 2 or more IoT devices of same or different networks. This can be achieved by different communication protocols like: MQTT, Constrained Application Protocol, ZigBee, FTP, HTTP etc.

Characteristics of IoT

  • Massively scalable and efficient
  • IP-based addressing will no longer be suitable in the upcoming future.
  • An abundance of physical objects is present that do not use IP, so IoT is made possible.
  • Devices typically consume less power. When not in use, they should be automatically programmed to sleep.
  • A device that is connected to another device right now may not be connected in another instant of time.
  • Intermittent connectivity – IoT devices aren’t always connected. In order to save bandwidth and battery consumption, devices will be powered off periodically when not in use. Otherwise, connections might turn unreliable and thus prove to be inefficient.

Desired Quality of any IoT Application

Interconnectivity.

It is the basic first requirement in any IoT infrastructure. Connectivity should be guaranteed from any devices on any network then only devices in a network can communicate with each other.

Heterogeneity

There can be diversity in IoT enabled devices like different hardware and software configuration or different network topologies or connections, but they should connect and interact with each other despite so much heterogeneity.

Dynamic in Nature

IoT devices should dynamically adapt themselves to the changing surroundings like different situations and different prefaces.

Self-adapting and self configuring technology

For example, surveillance camera. It should be flexible to work in different weather conditions and different light situations (morning, afternoon, or night).

Intelligence

Just data collection is not enough in IoT, extraction of knowledge from the generated data is very important. For example, sensors generate data, but that data will only be useful if it is interpreted properly. So intelligence is one of the key characteristics in IoT. Because data interpretation is the major part in any IoT application because without data processing we can’t make any insights from data. Hence, big data is also one of the most enabling technologies in IoT field.

Scalability

The number of elements (devices) connected to IoT zones is increasing day by day. Therefore, an IoT setup should be capable of handling the expansion. It can be either expand capability in terms of processing power, storage, etc. as vertical scaling or horizontal scaling by multiplying with easy cloning.

Each IoT device has a unique identity (e.g., an IP address). This identity is helpful in communication, tracking and to know status of the things. If there is no identification then it will directly affect security and safety of any system because without discrimination we can’t identify with whom one network is connected or with whom we have to communicate. So there should be clear and appropriate discrimination technology available between IoT networks and devices.

Sensitive personal details of a user might be compromised when the devices are connected to the Internet. So data security is a major challenge. This could cause a loss to the user. Equipment in the huge IoT network may also be at risk. Therefore, equipment safety is also critical.

Architecture

It should be hybrid, supporting different manufacturer’s products to function in the IoT network.

As a quick note, IoT incorporates trillions of sensors, billions of smart systems, and millions of applications. 

Application Domains

IoT is currently found in four different popular domains: 

Modern Applications

  • Smart Grids and energy saving

History of Internet of Things

How it works

“Over 20 years ago a few professors at MIT began describing the Internet of Things (IoT) which is a world where interconnected Internet-enabled devices or “”things”” have the ability to collect and share data without human intervention.” (Baltzan, pg. 3) To give a clearer explanation of what the Internet of Things actually is, we can describe it as a giant system that lets people all over the world interact with each other, as well as share and receive data on just about any topic that you could imagine. It is actually quite amazing if you think about the things that the Internet of Things can actually do. From talking and even seeing family and friends who are in a different country, to your yoga mat telling you how many calories burned among other information, the Internet of Things is a truly remarkable entity. There are many ways that consumers, alongside businesses can benefit from IoT, as well as things that have not even been thought of yet, all of which are and will be extremely beneficial and important for our future.

Consumers can benefit from the Internet of Things in many ways. They are able to purchase items and objects that the Internet of Things has created, as well as improve their daily life by using those things. There is an article on entrepreneur.com by Puneet Mehta that is titled “”8 Ways the ‘Internet of Things’ Will Impact Your Everyday Life.”” As the title suggests, it lists eight different ways that IoT will impact consumers lives, those being tuning your car, monitoring your health, energy consumption, driving and traffic jams, grocery lists, our morning alarm, monitoring your baby, and what’s on your body. A few of these are more helpful and/or important than others, such as monitoring your health and monitoring your baby. The article says, about monitoring your health, that there may be prescription bottles that will actually notify your care physician when they are running low. Doctors may also keep tabs on how often their patients are taking their medicine which will be helpful in many, many ways. The article also says, about monitoring your baby, “”through their smartphones, parents will monitor their baby’s breathing temperature and activity. Babies will don connected onesies that will send an alert when there is anything abnormal.”” (Mehta, web.) This would be extremely helpful in keeping babies safe and healthy, by notifying their caregivers of problems that they may not show symptoms of, or simply problems that are just easily missed. The article says that this is also possible with pets.

Businesses can also benefit from the Internet of Things. IoT can easily improve small business’s by making simple daily tasks easier, as well as help bigger businesses in the same way, as well as providing them with things that their customers may want to purchase. Salesforce.com gives us five ways that the IoT may make marketing smarter. These five ways are, “”Easy Exchange of Sales Data, Smarter CRM: Instantaneous Customer Analysis, Devices That Know They’re Dying, Predictive Social Media, and Imagining a 100% CTR (Click Through Rate)”” (salesforce.com) This same website says, “”When Facebook and Twitter first hit the scene several years ago, most marketers were less-that convinced that these new “”social media”” sites would be worth targeting. We all know how well that turned out. Today, 74% of brand marketers report that they see a noticeable increase in web traffic after investing a mere 6 hours a week in social media marketing efforts.”” (salesforce.com) This short paragraph is enough to show someone the incredible advance that the Internet of Things is making on technology as well as on mankind. It is also just a small part of how the Internet of Things is affecting business’s today. One particular business that has been impacted in a positive way by the internet of things is AT&T. They have a section on their website titled “”IoT Products and Solutions: Find what fits your business needs””. Then, listed under this caption is a tab for Networks, Platforms, Professional Services, Asset Management, Vehicle Solutions, Smart Cities, Internet of Medical Things, Global IoT, and IoT for Good. Under each of these tabs there are even more links to click on that will bring you even farther into the Internet of Things within the AT&T business. One that someone may find particularly interesting is the Internet of Medical Things. AT&T describes it as, “”Transform healthcare to human care with AT&T IoT Solutions. Innovations in connected health help people live better lives, improve the operational side of healthcare, and are beginning to impact clinical applications and telehealth at a higher rate.”” (AT&T, Internet of Medical Things)

If 50 years ago, someone said that mankind would come up with a device that would let you talk to someone who is thousands of miles away, let alone see that person, everyone would think that they were crazy. So just think about the crazy, unpredictable things that may be invented a short 50 years from now. “”The Internet of Things is reaching further into our daily lives by combining data from sensors in wearable devices and equipment with analytic programs to help improve the performance of individuals by gaining insights that were traditionally impossible to detect.”” (Baltzan, 3) As one could gain from this passage, the Internet of Things will be extremely important for our future because of all of the things that it can and will be able to help us with. This includes but is not limited to letting us know about illnesses, giving us real time information on health and fitness data such as calories burned, calories taken, weight lost, and muscle gained. There is no telling what else the Internet of Things will have in store for the future, and it seems as though it will be interesting as well as intriguing to see where it takes us.
