Abstract

High overhead is a limiting factor of Dynamic Source Routing(DSR) protocol applied for mobile ad hoc networks(MANETs).In this paper, a modification is proposed for basic DSR to enhance its performance. In the modified- DSR(MDSR), for a source destination pair, the destination responds to the first received route request packet(RREQ) with a route reply packet(RREP), and the subsequently received RREQs bearing same sequence number are responded only if the hop count is less than that of all the previously received RREQs. The performance of MDSR has been compared with that of basic DSR and simulation results show that MDSR reduces the overhead and the number of control packets.
