Cluster head selection algorithm for mobile wireless sensor networks

Cluster based routing protocols have significant impact on the energy dissipation and life time of wireless sensor networks (WSN). In this paper Basic Low Energy adaptive clustering hierarchy (LEACH) protocol has been modified with our proposed LEACH-MAE(LEACH-Mobile Average Energy based) protocol to overcome its shortcomings to support mobility along with the new average energy based Cluster Head selection technique. Our simulation in NS2 shows that proposed algorithm improves network life time up to 25 % as well as helps to maintain the equal distribution of energy resource among the sensor nodes.
