Multipath Routing Protocol for Reliable Data Transmission over Infrastructure-Less Mobile Network

Providing requisite QoS guarantees in wireless multihop networks is much more challenging than in wired networks. This is mainly due to its dynamic topology, multihop communication and contention for channel access. In particular, it is important for routing protocols to provide QoS guarantees by incorporating metrics like achievable throughput, delay, jitter, packet loss ratio, etc. In this paper, we have proposed and implemented a node-disjoint multipath routing protocol (NM-On Demand Distance Vector) based on on-demand distance vector routing protocol for reliable and efficient routing over Mobile Networks. Our proposed multipath protocol discovers all node-disjoint routes between a source and destination within a single route discovery phase. To prove the correctness and effectiveness of proposed approach, it is compared with other traditional routing protocols. Simulation results are provided which are generated using the Qualnet simulator for various scenarios to show the effectiveness of proposed approach.
