The Internet certainly become a part of the life of a social animal. It is a big room for people and knowledge. The Internet first emerged as the “Computer Internet.” It is a digital network where it is possible to incorporate several services on top of it, such as the World Wide Web. It was an age of information sharing. There were several social websites that kept individuals linked all the time. This has led to the Internet being loaded with individuals rather than data. Technology, on the other hand, has been progressing day by day. A period of “MobiComp” (mobile computing) has also begun [2–4].

Mobile internet services for 3G and 4G have now resulted in quicker internet connectivity and increased video call quality. Mobile computing and wireless technology have become inexpensive and have gained more popularity. Therefore, there was a new computer-Ubiquitous computing.

Figure 1.2 Growth of Internet of Things.

Intelligent space and minimal user participation are the subjects of this computing. Advances in technology have contributed to a reduction in size for smartphones and other portable devices. Ordinary mobiles and PCs have been replaced by smart phones, i-pads, laptops, and notebooks. There was also a shift in the device through which individuals access the internet. This, in turn, resulted in the configuration of sophisticated functions.

Devices were not only connected to the internet in such a situation, but also sensed, computed, and performed intelligent tasks. Later, physical items were programmed with identification tags such as bar code and RFID so that devices such as smart phones could scan them and upload their information to the internet. With the aid of a smart computer, this way of linking the real world with cyberspace contributed to the internet being called the “Internet of Things”. Figure 1.2 shows that it has its origins in mobile computing, ubiquitous computing, and IT [5]. Therefore, from the above, IoT transforms the view of connectivity from “any-time, anywhere” for “anyone” to “any-time,” any-place” for “any-thing”.
