Survey on localization of the Sensor nodes in Wireless Sensor Networks

The Wireless Sensor Networks is a group of nodes scattered in the network. Each node has certain processing capacity, memory. It shares the resources and information among the nodes. The example of these services includes mobile services, traffic monitoring, natural calamities, smoke detection and vehicle tracking applications. Sensor networks provides the fast sensing and make necessary actions to provide reliable transfer of information. The sensor node helps to provide the better gathering of data and it provides a backup through which the failure of one node is compensate by the other node. Sensor nodes require less energy, battery power, reduced cost easy node deployment
