Routing algorithm for optimal lifetime of wireless sensor network

Abstract

Advances in wireless sensor networks have led to many new routing protocols specifically designed for sensor networks where energy awareness is an essential consideration. Routing in wireless sensor networks has received increasing attention and research in recent years whereas most routing protocols concentrate on finding and maintaining routes in the face of changing topology caused by mobility or other environmental changes. The nodes in wireless sensor network have limited initial amounts of energy that are consumed at different rates while forwarding, receiving and processing messages and the intended receiver which can be more than one hop away. Energy aware routing protocols and algorithms have been developed to address the issue of limited energy of the nodes in a wireless sensor networks. These energy aware routing protocols tries to ensure that the time until the batteries of the nodes drain-out is maximized. This project considers and examines energy aware routing algorithms with the goal of establishing one which maximizes the lifetime of a wireless sensor network. The comparison is performed by evaluating and modeling the routing algorithms and verifying the performance through simulation.
