Analysis of Prominent Reactive Routing Protocols using Self Created Network Scenario

Abstract — Mobile Adhoc Network is characterized by multi-hop wireless connectivity and dynamic topology. The mobile nodes in this network communicate with each other without established infrastructure. Since the wireless links are highly error prone and can go down frequently due to mobility of nodes, therefore, routing in MANET is a critical task due to highly dynamic environment. In this research paper, pattern analysis of two on-demand routing protocols has been done by presenting their functionality. A simulation model with TCP and UDP connections has been developed to study inter-layer interactions and their performance implications. The performance differential parameters have been analyzed using metrics like PDR with varying speed and pause time. Based on the simulation results, recommendations have been made about the significance of either protocol in various situations. The study reveals that DSR protocol outperforms AODV protocol under low as well as high mobility situation in case of UDP as well as TCP connections. AODV protocol also starts performing well under high mobility situation. DSR protocol outperforms AODV protocol when the connections are through UDP and this analysis is independent of pause time. AODV protocol outperforms the DSR protocol when the connections are through TCP and the pause time is increased up to a large extent.
