PERFORMANCE EVALUATION OF ROUTING PROTOCOLS IN MANETS

Abstract

Mobile Adhoc Network (MANET) is a decentralized independent wireless system that is selfconfigured
with a collection of mobile communication node that moves randomly. Challenges
such as routing, power management, frequent topology changes, and security are faced by
network developers and designers. Routing is one of the core factors that have great influence
on network performance, its discovery and maintenance are critical issues. Several studies have
been done on the performance evaluation of routing protocols using different evaluation
methods. In this paper, we evaluated the performance of DSR, OLSR and GRP, a proactive,
reactive and hybrid Adhoc routing protocols respectively using OPNET Modeler Simulator.
The performance of these routing protocols is analyzed by Delay, Throughput, Network load,
Retransmission Attempts and Data Dropped. The comparison analysis has been carried out
about these protocols, simulation results shows that OLSR outperformed both GRP and DSR
routing protocols.
