Wireless Sensor Networks (WSNs) usually consists of a large number of nodes called sensor node that bring themselves together to form a wireless network. However, the major fact that sensor nodes run out of energy quickly has been an issue and many power efficient routing protocols have been proposed to solve this problem and seniority of the network. This is the reason why routing techniques in wireless sensor network focus mainly on the accomplishment of power conservation. In this paper, the authors intend to proposes the algorithms for cluster formation and Cluster Head (CH) selection for prolongs the network lifetime.
