Journal of Information and Communication Technologies The Dynamic Source Routing (DSR) is a routing protocol for Mobile Ad-hoc Networks (MANETs). DSR typically utilizes mechanisms for route discovery and route maintenance. It depends on the route maintenance mechanism to increase delivery ratio, reduce the routing overhead and route discovery latency. The mobility of nodes can cause routes to become unfeasible and data packets may be dropped. In this paper, we propose a new packet salvaging approach to route maintenance mechanism. This mechanism is invoked only when a failure link is detected during data transmission; at the same time, salvaging process starts by the node which cannot send a packet to next hop in the source route. As soon as first attempt has failed, intermediate nodes will attempt to salvage data packets rather than waiting for a new route discovery mechanism. Data salvaging process works by adding information into the route error packet, which aid upstream nodes to find alternative route for prevent data packets from drop. To evaluate our approach, we have added it to the DSR protocol and evaluated its impact on the performance using detailed simulations. The result show that the proposed salvaging approach significantly improves the performance of DSR in terms of packet delivery ratio, routing overhead and dropped packets. 1-6 |
