Energy Efficient Communication in Mobile Sensor Networks Based on Clusters

Mobile Sensor Networks (MSN) energy of the battery operated nodes is the most vulnerable resource of the MSN. In a clustering approach, the Cluster Head node loses a significant amount of energy during transmission to base station. So the selection of Cluster Head is very critical. In this work a centralized protocol for Cluster Head selection in MSN is discussed, which is run at the base station, thus reducing the nodes' energy consumption and increasing their life-time. The primary idea is implemented using a fuzzy-logic based selection of Cluster Head from among the nodes of network, which is concluded depending on two parameters, the current energy of the node and the distance of the node from the base station. The simulation results show increasing the network lifetime.
