Energy Efficient Cluster Head Selection Based On Mobile Sink Using Leach Protocol In Wireless Sensor Networks

Abstract

The energy near the static sink normally suffers from energy depletion issue since the node near the sink propagates signals to other nodes and acts as a convener, which leads the energy dissipation of sensor nodes near to the mobile sink, resulting in a network energy hole. In order to resolve these concerns, we have proposed a protocol known as Improved Mobile Sink Low Energy Adaptive Clustering Hierarchy (IMS-LEACH) protocol toreduce the problems with wireless sensor networks and to extend the life of sensor nodes. The proposed mechanism uses two methods, the first method organizes the cluster and a cluster head is selected for every cluster. And in the second technique, the selected cluster is in charge of gathering data from the cluster's sensor nodes and eventually transmitting it to the sink node. In the proposed methods Sink Node can move to any sensor node in a cluster to gather data and it leads to minimized energy consumption compared to other protocols.
