Group Source Routing Protocol with Selective Forwarding for Mobile Ad Hoc Networks

In this paper, we have proposed a group dynamic source routing protocol, GDSR, for mobile ad hoc networks with high mobility. We focus on pursuing routing stability and making a fast recovery of link failure. Nodes in a network are divided into clusters, each being assigned a unique cluster I abel. A routing path is represented by a source route including a sequence of cluster labels, and the nodes having an identical cluster label are responsible for delivering packets cooperatively to the cluster whose label is the next one in the source route. We have also employed a distributed self-pruning algorithm DSP to prevent intermediate nodes from relaying RREQ unnecessarily, thus reducing considerable overhead. We compared our protocol with some existing ones and the result is proven to be highly dependable.
