Performance Investigations of HBO Based Sink Mobility Aware Heterogeneous Protocol of WSN

Wireless Sensor Network (WSN) has always been the dominating technology serving an array of solutions including civil, defense and industrial monitoring, control and decision purposes. Routing decides for the communication to be effective or non effective depending upon the energy saving while transferring data packets to the sink. There are two modes of network; heterogeneous and homogeneous. Heterogeneous network has focused mostly on the cluster head selection. Sink mobility in the heterogeneous network has not been touched much, it is observed it makes the network much energy efficient. The optimization in the network leads to the stability of network at much higher level. In this paper, sink mobility is optimized using Honey Bee Optimization (HBO) technique in the network by considering the parameters of energy and distance. The stability period of the proposed protocol has enhanced to 33 % by covering 2928 rounds as compared to 2033 rounds of the iMBEENISH protocol. The network lifetime has enhanced to 15000 rounds as compared to 14084 rounds of iMBEENISH protocol. It accounts to the 6% improvement by proposed protocol.
