Prolonging Wireless Sensor Network Lifetime Using Routing Protocol

Prolonging network lifetime is one of the challenging issues of Wireless Sensor Networks (WSN). Many techniques have been proposed to achieve a longer battery life of the sensor nodes. In this paper, we focus on the routing technique to improve the battery life to extend the network lifetime. Our protocol is based upon the two existing protocols, namely, LEACH (Low-Energy Adaptive Clustering Hierarchy) and PEGASIS (Power Efficient GAthering in Sensor Information Systems). By extracting the fundamental working principles of these two routing techniques, we propose a new protocol, which provides increase network lifetime compared to these existing basic protocols.
