Performance Comparison of Geographic LAR1 with On-demand AODV and DSR Routing Protocols for MANETs

Abstract

MANET is a self organizing, infrastructure-less network, that consist number of low power mobile nodes connected by wireless radio frequency signals. These nodes in this dynamic environment move freely in any direction, which leads to change in network topology. It is very difficult to recharge or replace the battery of the nodes. To maximize the battery life and lifetime of the network, the nodes are required to be energy conserved. The mobile node energy can be affected by the performance of the routing protocol. We have considered three routing protocols, one is location based protocol - LAR1 and the other two are non location based protocols - AODV and DSR. The energy performance metrics, routing power and residual energy in all the three modes –transmitting, receiving and idle mode are evaluated using these routing protocols in Mobile Ad-hoc Networks and also other performance metrics in application layer are evaluated, which are throughput, end-to-end delay and average jitter. The simulation is carried out by using EXata -5.4.
