It is very hard, but important to sustain path stability for a reliable communication in mobile ad hoc networks. We propose a novel source routing protocol that establishes a group path with virtual multiple paths to enable a robust communication. The entire mobile nodes form a disjoint set of clusters: Each has its clusterhead as a cluster leader and a unique cluster label to identify itself from other clusters. A group path is a sequence of cluster labels instead of nodes and the nodes with the same label collaborate to deliver packets to a node with next label on the group path. We prove by resorting to simulation that our proposed protocol outperforms the existing key routing protocols, even for a network with a high node mobility and a high traffic.

A variety of routing protocols targeted specifically at mobile ad-hoc network environments have been developed. Mobile ad-hoc network is a self-organizing temporary network, operating without the aid of any established wired infrastructure. The proposed protocol supports seamless communication services between the mobile hosts within a mobile ad-hoc network environments. In particular, our protocol makes faster route re-establishment possible by maintaining multiple paths in each mobile host, and also, the protocol provides reliable communication environments. We compare the performance of RWP model with that of LW model. This paper shows delivery ratio with single path and non-disjoint multiple path according to mobility model and node numbers.
