The multipath routing in mobile ad hoc networks is difficult because the network topology may change constantly, and the available alternative path is inherently unreliable. So far, much of the effort of multipath routing has been focused on using the predefined alternate path when a relay on the primary path has failed regardless of the availability of the alternate path. This reactive route handoff can increase the overhead for frequent route discoveries. In this paper, we propose a low overhead multipath routing scheme which utilizes an alternative path to feedback the path state information. Accordingly, it can proactively give up the primary path before it breaks and use the current candidate path as primary path. The results show that a significantly better performance than the single path routing and traditional multipath routing can be achieved in terms of routing overhead.
