The Internet of Things, or IoT, is defined as a worldwide network of “things” that include identifiable devices, appliances, equipment, machinery of all forms and sizes with the intelligence to seamlessly connect, communicate and control or manage each other to perform a set of tasks with minimum intervention.
As it is more growing nowadays, the goal of IoT is to enable things to be connected any time, any place, and with anything or anyone. IoT is not a single technology, but a concept. IoT research has its roots in several domains, including Radio-Frequency Identification (RFID), Machine-to-Machine (M2M) communication and Machine-Type Communication (MTC), Wireless Sensor and Actuator Networks (WSAN), Ubiquitous Computing, and the Web-of-Things (WoT). This is perhaps one reason that everyone calling it The Internet of Everything, or IOE.
We are now at the beginning of the third wave as wearable devices—fitness bands, watches, and eyeglasses, automobiles, appliances, and sensors connect to the Internet, bringing the number of connected devices into tens of billions, said the report. While the fixed Internet connected 1 billion users via PCs, and the mobile Internet connected 2 billion users via smartphones (on its way to 6 billion), IoT is expected to connect 28 billion “things” to the Internet by 2020.
This rapid growth is being driven by a steep decline in prices of components such as RFID chips and the increasing ubiquity of broadband access.
