摘要: Battery power is a critical resource of Wireless Sensor Networks (WSNs). Therefore, an effective operation WSNs depend upon the efficient use its battery resource. Cluster based routing protocols are proven to be more energy as compared other protocols. Most cluster protocols, especially Low Energy Adaptive Clustering Hierarchy (LEACH) protocol, follows Dynamic, Distributed and Randomized (DDR) algorithm for clustering. Due randomness present in clustering algorithms, number heads generated varies highly from optimal count. In this paper, we approach which attempts control LEACH's algorithm. This makes head count stable. NS-2 simulation results show that proposed improved First Node Death (FND) time Last (LND) by 21 24 % over LEACH, 10 20 Advance LEACH (ALEACH) 5 35 with Deterministic Head Selection (LEACH-DCHS) respectively.
