Abstract

A mobile ad-hoc network (MANET) is usually power constrained due to the limited battery energy on each node. For MANETS, energy efficiency is crucial for the design of new routing protocols. In this paper, a new energy-aware routing algorithm, called Energy Saving Ad-hoc On-demand Distance Vector (ESAODV) routing, is proposed. In the route discovery process of ESAODV, intermediate nodes estimate the current average energy of the network (CAEN) as a comparison threshold to determine how to respond to the received route request (RREQ) packets. After that, the effects of ESAODV on network performance are addressed. Analytical and simulation results show that the proposed ESAODV can effectively protect the energy-overused nodes and can greatly prolong the network lifetime.
