Performance Analysis of AODV, OLSR and GRP Routing Protocols in MANET

Abstract

This paper aims to compare performance of three routing protocols for Mobile Ad-Hoc networks (MANET’s). A Mobile Ad-Hoc Network (MANET) is a collection of wireless mobile nodes forming a temporary network without using any centralized access point, infrastructure, or centralized administration. In present study, a comparison of reactive routing protocol i.e., Ad Hoc On-Demand Distance Vector Routing (AODV), proactive routing protocol i.e., Optimized Link State Routing (OLSR) and hybrid routing protocol i.e., gathering-based routing protocol (GRP) has been made on the basis of throughput, delay and network load with increasing in number of nodes in the network. Authors have used OPNET Simulator from Scalable Networks to perform the simulations. Three routing protocols are being analysed on the above mentioned parameters and it can be concluded that OLSR performs remarkably better than AODV and GRP on prevailing node increasing in the network.
