Abstract

The Dynamic Source Routing (DSR) is a routing protocol for Mobile Ad-hoc Networks (MANETs). DSR typically employs mechanisms for route discovery and route selection. The route selection method of DSR is based on the shortest route; it is always complicated to meet the need of the changing topology of MANET. As a result, it increases the number of the failure route in node’s route cache. In this paper, we propose a new algorithm for route selection in DSR protocol. It calls Fresh Shortest Route (FSR) Algorithm. FSR uses the freshest-short route as routing metric. During the route selection process, FSR gives the priority for route that reply by the destination node rather than intermediate nodes. If there is no route reply from the destination node, the source node will select the shortest route in its route cache regardless of the source of route reply. As a result, the FSR algorithm was added to DSR protocol, as it is implemented in GloMoSim simulator and compared to standard DSR protocol. The results show that the FSR algorithm significantly improved the performance of DSR protocol in terms of the packet delivery ratio, routing overhead, dropped packets, and number of link breaks.
