Abstract :
We propose a multipath routing protocol for mobile ad hoc networks (MANETs), which combines split multipath-dynamic source routing (SMP-DSR) and shortest multipath source routing (SMS) and changes those backup paths selection criteria. Our proposed scheme improves the transmission success rate and the energy consumption by considering two features. One of the feature is to construct the least hop backup paths without the failed link away. The other feature is to reduce the packet drop by using the packet salvaging method. By providing the alternate paths to the intermediate nodes of the primary path, the proposed scheme ensures to salvage the packets that might be lost at the intermediate nodes. Therefore, hop counts of backup paths and data packet loss are reduced. It is shown by simulations that our scheme improves the transmission success rate and the energy consumption efficiency in MANETs.
