ABSTRACT

In this paper, we propose a novel approach “Routing based on Best First Search Technique (RBFS)” to improve the performance of Dynamic Source Routing (DSR) for mobile ad-hoc wireless networks. The proposed scheme tries to reduce broadcasting of Route Requests during routing. We investigated the QOS metrics namely Average jitter, Average end-to-end delay, Packet delivery ratio and Throughput in various simulation scenarios by varying network size. The simulation results show that the proposed approach achieves better performance than DSR when Average End-to-End delay and Average Jitter performance metrics are considered.
