摘要：This paper would study the DSR routing technology based on multiple description coding and communication distance between nodes in vehicle ad hoc network. This routing technology based on routing protocol DSR, aims to cope with the characteristics of dynamic network topology, high-speed motion of vehicle, unpredictable direction and speed of vehicle in vehicle ad hoc network. This technology improves the discovery and reply process of DSR route through multiple description coding technology and residual energy of nodes. The vehicle nodes measure the one-hop communication distance between nodes according to the attenuation degree of signals and the original node chooses the main path according to RREP messages. Sending and receiving routing message through multiple-description technology would reduce the overhead of routing request.Simulation experiment analysis indicates that the improved DSR routing technology has the better performance in terms of end-to-end delay, packet delivery ratio and routing request overhead.
