Review Paper on Wireless sensor network in IoT

Abstract: The IoT (Internet of Things) is the network in which physical devices, equipment, sensors and extra objects can communicate between themselves without human involvement. The WSN (Wireless Sensor Network) is a dominant component of the IoT, which has multiplied into numerous different applications in real-time. The IoT and WSNs now have many critical and non-critical applications impacting almost every area of our everyday life. Wireless sensor networks with the mobile sink can support to prevent the hot-spot problem and improve the network lifetime. Nevertheless, in practice, the courses of the sink cannot ideally change due to the obstacle of the environment or the necessity of the application.

Keywords: Internet of Things (IoT), Wireless Sensor Networks (WSN), Energy-efficiency, Data Aggregation.
