Abstract-In Wireless Sensor Network, the energy efficiency is the key issue for designing the protocol because sensor nodes have one time battery backup. There are many modern protocols which extend the lifetime of the wireless sensor network by efficiently using battery power of the sensor node. In this paper, we propose a new strategy and protocol Energy Level Bases Stable Election Protocol (ELBSEP) in Wireless Sensor Network. We analyze and compare the performance and results of modern protocols like LEACH, SEP, ESEP, TEEN and TSEP with ELBSEP. The simulation result shows that performance and throughput of our proposed protocol gives the effective and significant energy efficiency as well as more network lifetime compared to other protocols.
