Executive Summary

DSR Protocol offers a very effective routing mechanism in Wireless Mesh Networks. But the performance deteriorates when network is subjected to large amount of traffic. In this paper the authors have proposed modifications in DSR protocol, wherein congestion in the network is controlled by reducing the RREQ packet retransmission by the source node, and reducing the number of dropped packets by managing buffer space. Simulations done of Qualnet Network Simulator shows significant improvement in throughput, and reduction in number of packets dropped, and jitter.
