Performance Enhancement of Dsr Protocol with Congestion Avoidance Mechanism for Mobile Ad Hoc Networks

چکیده
Streaming multimedia applications over Mobile Ad Hoc Networks (MANETs) create new challenges to routing protocols in terms of stringent performance requirements. Many routing protocols that have been proposed in the past could not completely address these issues. In the present paper, the original DSR protocol is modified to provide multi-path data transfer during the periods of congestion. NS-2 simulation was used to evaluate the performance of the modified DSR in predefined mobility scenarios. The performance was evaluated using throughput and end-to-end delay and compared with original DSR. The results showed that a significant improvement in the performance of modified DSR was achieved with the use of multi-path routing and congestion avoidance mechanism.

متن کاملAn Adaptive Congestion Control Mechanism for Streaming Multimedia in Mobile Ad-hoc Networks
In mobile ad hoc networks, most of the present routing protocols are designed to have congestion aware, but not congestion adaptive. The way in which the congestion is handled results in longer delay and more packets to be lost for streaming multimedia. When a new route is needed, the routing protocols require a significant overhead in finding it. Mobile Ad hoc Networks shows unexpected behavio...
