Enhanced DSR: An efficient routing protocol for MANET

An ad-hoc network is a group of wireless mobile nodes which are self-creating, self-organizing, and self-administering. In these networks, selection of routing protocol is an important concern, which may enhance the performance of ad-hoc networks in terms of residual battery, average end to end delay, average jitter and throughput. To fulfill this aim, an efficient algorithm viz. enhanced DSR (DSR1) is proposed in the present work. This algorithm reduces the flooding of RREQ (route request) packets in the network which results in the reduced congestion and energy consumption. In this when a node receives a RREQ packet it checks, its own residual battery, received signal strength and speed. If the defined thresholds for the node for these mentioned parameters satisfy then the RREQ packet will be forwarded in the network. If it doesn´t meet the defined threshold, the RREQ packet will be discarded. Hence the proposed algorithm prohibits the unnecessary flooding of RREQ packets. This results in the improved system performance.
