A cluster-based multipath dynamic source routing in MANET

Numerous studies have shown the difficulty for a routing protocol to scale to large mobile ad hoc networks. This article proposes a cluster-based multipath dynamic source routing in MANET (CMDSR) that is designed to be adaptive according to network dynamics. It uses the hierarchy to perform route discovery and distributes traffic among diverse multiple paths. The CMDSR is based on a 2-level hierarchical scheme: the 1-cell cluster and 2-server cluster. The main idea of our proposition is to transfer the route discovery procedure to the 2-server level to prevent the network flooding due to the DSR route discovery. Thus, route discovery does not require flooding mechanism and overhead is minimized and improve the networks scalability.
