A tremendous shift of technology from the Internet world to the intelligent world is conveyed by the trending phrase “Internet of Things”. As modern societies have turned to round-the-clock connectivity, IoT fits their needs. Recently, many researchers have redefined the term IoT according to the applications developed. It includes transportation, healthcare, mining and many more. A mathematical language of IoT is expressed by the conceptual framework of 2020 as [7], IoT= Sensor + Network + Data + Services.

IoT services will be gained from all living and nonliving things which either request or offer a service. The inter-connectivity between all the things is made possible with microcontrollers, sensors and actuators. IoT provides promising smart solutions which have arisen due to dramatic urbanization as shown in Figure 1.1 [8]. Several scientific and engineering applications have emerged rapidly with the help of IoT. Solutions on IoT can be addressed with the recent technologies such as Robotics, Radio-frequency identification (RFID), Wireless Communication, Cloud Computing and Micro-Electromechanical Systems (MEMS).
