Bharathi M. A, B. Vijayakumar, D. H. Manjaiah · 2013
The area of wireless sensor network has been researched for more than a decade ,but no better solution is yet found for retention of cumulative lifetime of the network. Hence, after digging down the possibility of performing energy optimization, this paper is based on potentials of biologically optimized algorithm targeting the lifetime of network. The paper introduces a newly designed algorithm (Elephant Swarm Optimization-ESO) that is based on unique cognitive and social behavior of elephant, where it was strongly felt that adoption of their patterns in social behavior can highly be formulated in the area of energy optimization in wireless sensor network. The proposed algorithm is empirically designed in Matlab and simulation results were compared with frequently used LEACH protocol, to observe that the proposed ESO protocol outperforms LEACH on the basis of network lifetime, packet delivery ratio and residual power.
