HSR: A New Lightweight Hybrid Source Routing Protocol for Mobile Ad Hoc Networks

In Mobile Ad-hoc Networks, routing is the most vital criteria on which the performance of the network dependswhich can easily be calculated by the parameters like packet delivery fraction, delay, overhead and the number of packets received. Abundant routing protocols have been introduced to enhance the performance under various specific scenarios. In this paper, we pro-pose an innovative technique to improve the data delivery along with effective failure detection mechanism that is lightweight hybrid source routing (HSR) protocol. . The problem of proactive and reactive methods when they are used individually is the main motivation to introduce and implement this novel technique. By this technique we can improve the QoS in MANET as compare to the proactive source routing. Our tests using computer simulation in Network Simulator 2 (ns-2) indicate that the delay in HSR is only a fraction of the delay of these baseline as well as light weight psr protocols, and HSR yields similar or better data transportation performance than these baseline as well as psr protocols.
