

WSN are used to collect data from the environment. They consists of large number of sensor nodes and one or more Base Stations. The nodes in the network are connected via Wireless communication channels. Each node has capability to sense data, process the data and send it to rest of the nodes or to Base Station. These networks are limited by the node battery lifetime.

Problem Statement
 

If the BS is setup outside the sensing region, then routing can easily be managed in clustering. Some of the work has been done using ring zone model, in which the BS lies at the center of the network.
