Performance Evaluation of CBR and TCP Traffic Models on MANET Using DSR Routing Protocol

The science of computer networking and the proliferation of mobile devices enable the capabilities of communicating with each other even in areas with no pre-existing communication infrastructure. Traffic and mobility models play an important role in evaluating the performance of these networks, despite criticism and assumption from various researches on TCP’s weaknesses on MANET. A simulation was carried out to evaluate the performance of CBR over TCP on MANET using DSR routing protocol. Although CBR and TCP have significant different manufacture behaviour on MANET, these differences lead to significant performance of CBR over TCP with better throughput and less average maximal end-to-end delay. DSR was able to respond to link failure at low pause time, this led to TCP’s performance in packets delivery.
