Multipath-Based Segment-by-Segment Routing Protocol in MANETs

We propose a multipath-based segment-by-segment routing protocol in mobile ad-hoc networks (M-SSR). In M-SSR, a path is divided into multiple segments, in each of which multiple node-disjoint paths are discovered and routing maintenance can be performed independently. The proposed protocol can decrease congestion, optimize bandwidth and improve the sharing rate of channel by using multiple paths to transmit data packets in parallel. It uses segment-by- segment scheme to decrease routing control overhead and improve the network scalability. Simulation studies show that the proposed protocol can balance the load of the network and can be adaptive to the change of the network topology effectively, and also improve the survivability, stability and success ratio for routing.
