1. Internet of Things – what is it?

Once I heard the phrase “the concept of the Internet of things.” From one wording, it immediately became clear that we are talking about things that have access to the network. Then I was not particularly interested in this area. After some time, I heard the phrase: “Internet of Things …”.

Even then I thought that the person had made a slip, because the phrase was kind of ridiculous. But then more and more often I began to hear the same phrase, while my brain refused to perceive it, until I finally decided to read about it in more detail. Having read only the original name – Internet of Things, I immediately realized that hearing “Internet of Things”, I was trying to connect it with the concept of “Internet of Things”, and not with the “network of things”.

Actually, because of such a funny situation, I became interested in this issue. By the way, I wonder if this phrase seemed ridiculous to me alone at first glance, or did everyone have exactly the same feeling.

Some interesting facts from history
Let’s see what we have interesting in history has been associated with the Internet of things. Of course, there are a lot of facts: the creation of the Internet itself, and the creation of the first page on the network, etc., probably cannot be enumerated, so I will write the most interesting, as it seems to me, and most closely related to the Internet of things.

In 1926, Nikola Tesla in an interview for Collier’s magazine said that in the future radio will be transformed into a “big brain”, all things will become part of a single whole, and the tools that make this possible will easily fit in your pocket.

In 1990, an MIT graduate, one of the fathers of the TCP / IP protocol, John Romkey created the world’s first Internet thing. He plugged in his toaster.

The term “Internet of Things” itself was coined by Kevin Ashton in 1999. In the same year, the Auto-ID Center was established, focusing on radio frequency identification (RFID) and sensor technologies, thanks to which this concept has become widespread.

In 2008-2009, there was a transition from the “Internet of people” to the “Internet of things”, i.e. the number of items connected to the network has exceeded the number of people.

What is the Internet of Things?

There are many definitions of the Internet of Things. We will understand the Internet of Things as a single network that connects the objects of the real world and virtual objects around us.

According to one of the definitions, from the IoT point of view, “thing” is any real or virtual object that exists and moves in space and time and can be uniquely identified [interesting, by the way, how does a virtual object move in space?

Those. The Internet of Things is not just a set of different devices and sensors interconnected by wired and wireless communication channels and connected to the Internet, but it is a closer integration of the real and virtual worlds, in which communication takes place between people and devices.

It is assumed that in the future “things” will become active participants in business, information and social processes, where they will be able to interact and communicate with each other, exchanging information about the environment, reacting and influencing the processes taking place in the world around them, without human intervention.

According to Rob Van Kranenburg, the Internet of Things is a “four-layer pie”.

Level 1 is associated with the identification of each object.

Level 2 provides with a service for servicing the needs of the consumer (can be viewed as a network of one’s own “things”, a particular example is “smart home”).

Level 3 is associated with the urbanization of urban life. Those. it is the concept of a “smart city”, where all the information that concerns the residents of this city is pulled into a specific residential area, into your house and neighboring houses.

Level 4 – sensory planet.

In other words, the Internet of Things can be viewed as a network of networks in which small loosely connected networks form larger ones.
