Abstract: The DSR protocol is first analyzed. Then, a simple independent multipath routing protocol is proposed based on DSR. Only the destination nodes respond to the routing request, and the middle nodes could only pass on the routing request once. In doing so, it not only reduces the number of routing packets but also provides independent routes for as many destination nodes as possible. The DSR protocol is compared with the SIMR algorithm under NS2 in overhead routing, packets loss rate and average endtoend delay. The results show that the performance of the SIMR algorithm is better than the DSR routing protocol.

Key words: Ad hoc, DSR, independent multipath , routing protocol
