Wireless Sensor Networks (WSNs) consist of multiple nodes, usually tens to thousands, that are deployed to gather useful information from the environment/field. These nodes share information and carry out cooperative processing by communicating through wireless channels. These Wireless Sensor Nodes are generally grouped in clusters to increase the efficiency of the network and enhance the scalability of the network system. However, since the nodes have limited power capabilities, limited computation power and finite battery life, it becomes critical to conserve the limited resources in order to increase the up-time of the network.
