Optimization of Performance Metrics of LAR In Ad-Hoc Network

Abstract

Routing in Mobile Ad-Hoc Network (MANET) is a crucial task due to highly dynamic network environment. In latest years, several routing protocols have been implemented. In recent developments, position-based routing protocols exhibit better scalability performance and robustness against frequent topological changes such as, Location-Aided Routing (LAR) protocol. In this paper, developments of performance-metrics using LAR have been reported. Using these developments, LAR protocol has been found to be better than other protocols like DSR in MANETs of different scenario. This is because of already available location information of the nodes in network while it is based upon source routing as a DSR. Via LAR, performance metrics Packet Delivery Fraction (PDF), routing overhead, End to End (E2E) Delay, Non-Routing Load (NRL) and Number of lost (dropped) packets during route discovery can be optimized in dynamic Ad-Hoc networks.
