In this paper we consider a multipath extension to the dynamic source routing DSR protocol an on demand routing protocol for ad hoc wireless networks. This extension keeps two node disjoint paths between the source and destination of a routing process without introducing extra overhead Unlike other multipath extensions where node disjoint paths are selected at the destination or at the reply phase our approach generates two node disjoint paths during the query phase of the route discovery process by restricting the way the query packet is flooded Several optimization options are also considered Simulation is Conducted to determine the success rate of finding node disjoint paths
