Upgrading Performance of DSR Routing Protocol in Mobile Ad Hoc Networks

Routing in mobile ad hoc networks is a challenging task because nodes are free to move randomly. In DSR like all On-Demand routing algorithms, route discovery mechanism is associated with great delay. More Clearly in DSR routing protocol to send route reply packet, when current route breaks, destination seeks a new route. In this paper we try to change route selection mechanism proactively. We also define a link stability parameter in which a stability value is assigned to each link. Given this feature, destination node can estimate stability of routes and can select the best and more stable route. Therefore we can reduce the delay and jitter of sending data packets.
