Simulation Based Comparative Analysis of AODV, TORA and DSR Protocols

A mobile ad hoc network (MANET) consists of mobile nodes, connected by wireless links. The mobile nodes can receive and forward the data packets as a router, which make routing a critical issue in MANET's. In MANET's, different routing protocols are used to establish the route and data transfer takes place from source to destination through those routes. In this paper work, an attempt has been made to compare the performance of three on-demand routing protocols for MANETs: Ad hoc On Demand Distance Vector (AODV), Dynamic Source Routing (DSR) protocols, and Temporally Ordered Routing Algorithm (TORA) with respect to five performance metrics: Packet Delivery Ratio (PDR), Throughput, Normalized Routing Overheads, Error rate and MAC Collision rate. The performance differentials are analyzed using varying number of nodes. These simulations are carried out using the MATLAB. Simulation results show that the overall performance of AODV is better than TORA and DSR for all the observed parameters for the specified simulation environment.
