摘要：Ad hoc networks are characterized by multi-hop wireless connectivity, frequently changing network topology and the need for efficient dynamic routing protocols. The wireless mobile nodes in this network communicate with each other without centralized control or 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 recent years, several routing protocols have been proposed for mobile ad hoc networks and prominent among them are DSR (Dynamic Source Routing) and AODV (Ad hoc On Demand Distance Vector). In this research paper, a comparison of the performance of these two on-demand routing protocols has been done by presenting their functionality. An extensive simulation model having scenario of 20 nodes and 6 TCP/UDP connections has been used to study inter-layer interactions and their performance implications. A demonstration has been made that even though DSR and AODV share a similar on-demand behavior, the differences in the protocol mechanics can lead to significant performance differentials. The performance differentials are analyzed using packet delivery ratio with respect to varying mobility and pause time. Based onthe observations, recommendations can be made about the performance of either protocol
