Enhanced Clusterhead Selection Algorithm Using LEACH Protocol for Wireless Sensor Networks

WSN is now-a-days a vast field for research. Its growth increases day-by-day. Routing protocol with energy efficiency has been a challenging issue in the design of wireless sensor networks. Efficiency and security are two topics in the design of routing protocol for WSNs. Heinzelman, ET. Al. introduced a hierarchical clustering algorithm for sensor networks; called Low Energy Adaptive Clustering Hierarchy (LEACH).The new proposed scheme describes two new ways to select Cluster head. Analysis shows that the improved or enhanced LEACH protocol balances the energy expense, saves the node energy and hence prolongs the lifetime of the sensor network.
