Unicast Backtracking Route Recovery in ODMRP

摘要

The familiarity of Mobile Ad hoc NETwork (MANET) in the area of networking can be attributed to its ability of wireless communication and the lack of need for any fixed infrastructure. Hence, it can be deployed anywhere quickly. But achieving better transmission rate in MANET with mobile nodes is a challenging task so, several routing techniques have been given to increase the transmission rate. In the existing approaches, when the packet delivery is increased the overhead also increases in the network. The focus of our approach is to reduce the overhead and increase the packet delivery ratio. The proposed approach uses unicast backtracking link detection method to detect the link breakage and thus induces very less route recovery packets in the network. We compared our result with On Demand Multicast Routing Protocol (ODMRP), patch-ODMRP and resilient ODMRP. The parameters used for comparison are packet delivery ratio, jitter, and packet overhead. The simulation is done on Exata/Cyber 2.0 simulation tool. The analysis of results confirms that our approach retains the data transmission rate equivalent to patch-ODMRP with very less overhead.
