Vol. 15  No. 5  pp. 19-28


The mobile ad-hoc network (MANET) is a system of wireless mobile nodes, that can freely and dynamically self-organized in arbitrary and temporary network topologies, without the need of wired backbone or centralized administration, that why need for efficient dynamic routing protocols plays an important role. A variety of routing protocols targeted specifically at this environment have been developed and some performance simulations are made on numbers of routing protocols like Dynamic Source Routing (DSR), Ad-hoc On-Demand Distance Vector Routing (AODV) and Destination Sequenced Distance-Vector (DSDV) routing algorithm has been implemented. To the best of our knowledge, few published work is available in the literature, which compares as many criteria as we have done to evaluate the performance of the considered routing protocols. In this paper we perform extensive simulations on differences in the protocol mechanics can lead to significant performance differentials using ns-2 simulator. The performance differentials are analyzed using varying network load, mobility, simulation times, connectivity sources and network size under performance metrics. These simulations are carried out based on the observations we make recommendations about when the performance of either protocol can be best.
