Internet of things or internet of everything refer to the idea of thing (object), that are readable, recognizable, locatable, addressable through information sensing devices (sensor) and controllable via internet.
Things are physical objects with unique identifiers that are able to transfer data over the network. Examples of physical objects include vehicles, smart phones, home appliances, toys, cameras, medical instruments and industrial systems, animals, people, buildings, etc. [4]
Internet of Things is a new revolutionary and advanced technology where any object becomes smart object, and where they can communicate information about themselves without human intervention. The Internet of Things is expected to make a huge change in our lives; it will help us to perform our tasks and duties in a better way.
History and Evolution of IoT:
The very first idea of IoT started with Coca Cola vending machines in 1980s at the Carnegie Melon University, students from the department of computer science install micro- switches into the machine to see if the cooling devices was keeping the drinks cold enough and if there were available coke cans in the machine via internet. This first invention encourage further studies on interconnected machines. Later in 1990s, with a TCP/IP protocol John Romkey connected a toaster to the internet for the first time. [5]
In 1991 at Cambridge University, Scientist developed a system to check to amount of coffee available in the coffee machine. The idea was to use the webcam to take picture of the coffee pot three time a minute and send to local computer located in their lab so everyone could see the amount of coffee. [5]
In 1991, Kevin Ashton introduce the concept of the internet of things (IoT) in a presentation paper for Procter & Gamble. In the presentation, he explained the internet of things as a technology that connected devices Using RFID (radio frequency and identification) technology. [5]
In 2008, scientists from 23 countries were regrouped in Switzerland at the first international conference on the internet of things, to discuss about the RFID, short- range wireless communications and sensor networks.
2010 was the true birth of the internet of things according to cisco because of the number of the interconnected devices. They also said that the number of interconnected devices passed the number of people on earth. [5]
In 2015, the number of connected devices has significantly exceed the number of people. We can see in the figure above that in the present year (2020) they are 50 billion and the world population is 7.6 billion people. This show that the number of connected devices are six times more the number of human.
It is expected that in the future, all things will be able to connect to each other. Things not including just electronic devices but also books, shoes, foods, water etc. [5]
