Abstract

In this paper, we present our technique to improve the performance of DSR protocol by using ACK reply path as a backup route when an original route fails in Mobile Ad Hoc networks. In the traditional DSR, when the route is no longer in use, a backup route will be initiated to transfer data in route cache. However, if the backup route is also failed, it will affect the overall network performance. We modify the DSR so-called as Modified DSR protocol (MDSR) so that the source node can still receive ACK reply from destination node when an original route is broken, which means data packets can be transferred along with the ACK path. MDSR deploys the idea of TCP-BuS to solve unnecessary resending of lost data packets. We implement and perform our proposed model in NS2 and the results show that the performance of modified DSR is better than the traditional DSR protocol in End to End delay, packet delivery ratio and routing load.
