The Survey Paper on Wireless Sensor Network

Abstract

Wireless sensor network provide a new paradigm for sensing and sending information. Wireless sensor networks are used in monitoring and control applications. Current WSN typically communicate directly with a centralized controller or a satellite, thus communication between the sensor and controller is based on a single hoop. An ongoing area of research is, where WSN nodes or terminals that communicate with each other forming a multi-hop network. Such WSNs could change their topology dynamically when connectivity among the nodes varies with the time due to node mobility. The wireless sensor networks are the type of sensor networks which is used to sense the environmental conditions like temperature, pressure etc.
