An Energy-Efficient On-Demand Routing algorithm for Mobile Ad-Hoc Networks

Abstract

Mobile Ad-Hoc Networks (MANETS) are characterized by random, multi-hop topologies that do not have a centralized coordinating entity or a fixed infrastructure that may change rapidly over time. In addition, mobile nodes operate with portable and finite power sources. In this work, we propose an energy-efficient metric for MANETs to minimize energy consumption and increase the networkpsilas consistency. Earlier works mainly focused on the shortest path method to minimize energy, which might result into network failure because some nodes might exhaust fast as they are used repetitively, while some other nodes might not be used at all. This can lead to energy imbalance and to network life reduction. We propose an Energy Efficient Ad-Hoc On-Demand Routing (EEAODR) algorithm that balances energy load among nodes so that a minimum energy level is maintained among nodes and the network life is increased. We focused on increasing the network longevity by distributing energy consumption in the network. We also compared the simulation results with a popular previously proposed on-demand routing protocol in this area, AODV, to show the usefulness of our algorithm.
