OPTIMIZED SINK MOBILITY AWARE HETEROGENEOUS PROTOCOL OF WSN

Abstract

Wireless Sensor Network (WSN) has been extraordinary in facilitating human being by taking a control over the each aspects of modern technology. WSN has limited power constraints which makes it limited in its applicability. The routing if made energy efficient, sensor network might runs for longer duration. In the heterogeneous WSN, the main emphasis has been on the cluster heads selection by modifying the various probabilistic selection of CH. i-MBEENISH protocol is an improved version of BEENISH protocol with sink mobility incorporated in its operation. It has worked on the four levels of energy heterogeneity. The important aspect that it has worked on is the avoidance of penalizing the advanced nodes for the frequent selection as a cluster head. In this paper, sink mobility is optimized using Honey Bee Optimization (HBO) technique in the network by considering the parameters of energy and distance. HBO-iMBEENISH is proposed which outperforms iMBEENISH and MBEENISH protocols in terms of stability period and network lifetime.
