The Internet of Things (IoT) has been defined in a number of different ways in technical literature and popular media. Each definition reflects a different perspective and supports a different interest. While there is no universal definition of the IoT, these different definitions highlights IoT's common traits and can help illuminate its strenghts and weaknesses while giving us a good sense of the tremendous impact IoT has on our life.

Besides the lack of an agreed universal definition, it should be noted that defining the IoT is hard for many reasons. One reason is that the IoT has a large number of applications, from monitoring supply chains to stopping trains and lighting homes, which involves all economic and social aspects of daily life and changes the way humans interact with the world around them. Another reason is that the IoT involves software and hardware, a variety of protocols and standards, devices and networks, storage, analytics, automation, and many other topics such as Artificial Intelligence (AI), Big Data, Machine Learning, and Augmented Reality (AR), which makes it even harder to understand the IoT itself. Furthermore, concepts generally included in the IoT vision strongly relate to visions under other names such as Web of Things, Web of Goods, Internet of Everything, and Cloud of Things, while other concepts including Cyber Physical Systems (CPS), Industry 4.0, Machine to Machine Communications (M2M), System of Systems (SoS), and Made in China 2025 closely relates to IoT but should be considered as part of or complementary to the IoT.

IoT Definitions

Since the definition of the IoT is still evolving because technology and the ideas behind it change themselves over time, the definitions that follow provide illustrative concept definitions rather than tightly worded definitions.

A non-exhaustive list of definitions about the IoT.

The representation contains information, including the thing's identity; status; location; or any other business, social, or privately relevant information.

69The main idea behind the IoT is to bridge the gap between the physical world of humans and the virtual world of electronics via smart objects.

70We must first define what we mean by 'things.' It could be very simple objects or complex objects. Things do not need to be connected directly to the public Internet, but they must be connectable via a network (which could be a LAN, PAN, body area network, etc.). The IoT is the network of physical objects that contain embedded technology to communicate and interact with the external environment. The IoT encompasses hardware (the 'things' themselves), embedded software (software running on, and enabling, the connected capabilities of the things), connectivity/communications services, and information services associated with the things (including services based on analysis of usage patterns and sensor or actuator data). An IoT solution is a product (or set of products) combined with a service either a one-to-one or a one-to-many relation. Meaning one service is combined with one (set of) product(s), or one service is combined with multiple (sets of) products.F. Jammes, Association for Computing Machinery (ACM) (Feb 2016).

Conclusion

Since the term "Internet of Things" was first used in 1999 by Kevin Ashton, who was working on supply-chain optimisation for Procter & Gamble, people have been using the term IoT in the wild in many ways. The IoT term has been used from marketing buzz to research publications and conference titles. Everybody had a different view and opinion about IoT.

To date, the definition of the Internet of Things (IoT) is still evolving due to the evolution and convergence of multiple technologies and megatrends. The IoT technology itself is on a maturing stage, and it is being interpreted according to specific needs, interests, and technical bias. That's why we observe a lack of a common or unified definition of IoT.

Regardless of shifting definitions and predictions, the IoT is still a useful concept for considering the economic, technological, and social impacts of the world of Internet connected smart Things. Myriad of reports, books, and articles have discussed how this evolution will benefit humanity.

For us at RT, the Internet of Things (IoT) is basically: smart electromechanical Things connected to the Internet.
