Wireless Sensor Networks (WSN) are self-organizing system consists with tiny, battery powered sensor nodes with limited processing, storage and communication capabilities that are often deployed in very harsh and inaccessible environment in order to gather data about some phenomenon from the outside world. The cluster based architecture is an efficient way for extending the lifetime of a WSN. The message transfer between two cluster head consumes more power than, between a cluster head and an intermediate node, as the distance of communication is greater in former. The power consumption of node can be lowered by passing message through the intermediate nodes i,e. cooperative communication and hence prolonging the network lifetime.
