Performance Analysis of AODV, DSR and OLSR under Different Traffic Loads in OPNET

A Mobile Ad-Hoc Network is a special type of dynamic network where no infrastructure is required for communication. The mobile node uses multiple hops to communicate with one another across the network. In recent years, the development of routing protocols for MANET has been increased, but in literature only few realistic performance comparison among the protocols are available. This study compares the performance of three routing protocols (AODV, DSR and OLSR) over different traffic loads. The QoS metrics End-to-End delay, Throughput and Network load are considered for the analysis of the routing protocols. OPNET tool has been used for simulation.
