In this paper

we propose a new multipath routing protocol for ad hoc wireless networks-Multipath Source Routing (MSR)

which is based on DSR (Dynamic Source Routing).MSR extends DSR's Route Discovery and Route Maintenance mechanism to deal with multipath routing.Based on the measurement of RTT

we propose a scheme to distribute load between multiple paths.The simulation results show that our approach improves the packet delivery ratio of TCP and UDP

and reduces the end-to-end delay

packet loss rate and the queue size

while adding little overhead.As a result

MSR releases the network congestion quite well.
