Improvements on DSDV in Mobile Ad Hoc Networks

摘要：

To improve the packet delivery ratio of Destination- Sequenced Distance Vector (DSDV) routing protocol in mobile ad hoc networks with high mobility, a novel message exchange scheme for its invalid route reconstruction is proposed in this paper. When route becomes invalid due to link breakage, the node that detects the link breakage tries to create a new loop-free route through message exchange with its neighbors. When route reconstruction in one-hop area is not accomplished, the area of message exchange for invalid route reconstruction is enlarged gradually on demand. Simulation results show that compared with DSDV, it reduces the number of dropped data packets with little increased overhead at higher rates of node mobility.
