A success of any sensor based application is determined by the overall performance of the network. The performance of any such network is heavily depends on how good the network formation is achieved. The key phase of the network formation is cluster head selection. All the nodes are transferring their data to base station as well as to other nodes through cluster head. In wireless sensor network, dynamic cluster based routing approach is widely used. Such practiced approach, quickly depletes the energy of cluster heads and induces the execution of frequent re-election algorithm. This repeated cluster head re-election algorithm increases the number of advertisement messages which in turn depletes the energy of overall sensor network.
