Simulation Based Performance Comparison of AODV and OLSR Routing Protocols in MANET

This paper aims to compare performance of two 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. In present study, a comparison of reactive routing protocols i.e. Ad Hoc On-Demand Distance Vector Routing (AODV) and proactive routing protocols i.e. Optimized Link State Routing (OLSR) has been made on the basis of throughput, retransmission and data dropped, by increasing number of nodes in the network. We have used OPNET Simulator from Scalable Networks to perform the simulations. Two routing protocols are being analyzed on the above mentioned parameters and had been concluded that OLSR performs remarkably better than AODV on prevailing node increasing in the network.
