LRCA: Enhanced energy-aware routing protocol in MANETs

Abstract

Mobile Ad hoc Networks (MANETs) is power constrained since mobile nodes operate with limited battery energy. So battery life is also important research issue in the routing protocol design. During packet transmission over multi-hop nodes, if a node failed, it should be caused link failure and source node will perform route recovery. It results that increases time of route recovery and packet loss rate. The objective of this study is to reduce route failure caused by dead nodes which consume all the battery life. We propose a new routing protocol based on AODV which provides an ability of changing routes to neighbor nodes before some of intermediate nodes be shutting down. From extensive simulations, results show that possibility of cutoffs and time-delay caused by packet-loss have been decreased and also improve overall performance by comparison with original AODV. © Springer-Verlag Berlin Heidelberg 2006.
