Wireless sensor networks have high potential to be applied in almost every field of life. Lots of research is done which have led to many new protocols where energy efficiency is an essential consideration. Clustering is a significant technique to reduce energy consumption. In this sensors are organized into groups, so that sensors transfer information only to cluster-heads and then the cluster-heads transfer the aggregated information to the base station. In this paper we have modified SEP(Stability Election Protocol) by presenting efficient cluster head selection scheme based on current energy level of sensor nodes and applying second selection to modify the number of cluster heads to be near optimal and then using dual transmitting power levels for cluster members.

Keywords: Balanced, Dual power level, Current energy, Stability Period
