In this paper, with an objective to increase stable region of WSN, stability enhancement for LEACH (SE-LEACH) protocol is propound which is capable of balancing the load ensuring all nodes dissipate power in similar fashion. Since best candidate selection is utmost requirement to play the role of cluster head, the selection criteria considers node density, residue energy, farness from base station & power dissipation if chosen as cluster head. Also, non-cluster head nodes elect their cluster head on the basis of residual energy, node density, the power it will dissipate during the round and distance to that cluster head. Simulation experiments are performed for two cases wherein a base station is kept at the center of the network in one hand and at far off distance on the other hand. Simulation results are compared with LEACH and MODLEACH which validate the extension of stability region and exhibit load balanced network for proposed protocol.
