Energy aware AODV (EA-AODV) using variable range transmission

Abstract

Energy conservation is an important issue in Mobile Ad Hoc Networks (MANETs) as most of the nodes are powered by a battery source which has limited energy reservoir and it also becomes very difficult to recharge or replace the battery of the nodes. Existing MANET routing protocols s. a. DSR and AODV use common transmission range for transfer of data and does not consider energy status of nodes. This paper discusses a new energy aware scheme (EA-AODV) based on AODV using variable transmission range. The protocols are simulated using Network Simulator-2 and comparisons are made to analyze their performance based on energy consumption and network lifetime metrics. The results show that EA-AODV makes effective node energy utilization. © 2012 Springer-Verlag GmbH.
