Study of DSR Routing Protocol in Mobile Adhoc Network

An adhoc network is a collection of wireless mobile nodes dynamically forming a temporary network without the use of any preexisting network infrastructure or centralized administration. By presenting a detailed study of DSR with its characteristics and performances, this study generalizes the lessons learned from DSR so that they can be applied to the many other new routing protocols that have adopted the basic DSR framework. The improvement is done in route reply (RREP) method. During route reply when more than one route replies are about to reach to source there are high chances that they create congestion at the last point. This congestion is a cause for possible collisions. We tried to reduce this possibility of collisions. We propose to include delay in RREP when RREP is One hop away from the source. We did simulation for the proposed scheme in NS-2. Simulation results revealed that the proposed scheme performs better than original DSR for collision.
