Low-delay Routing Algorithm Research Based on V2V

In the Vehicular Ad-hoc Network, delay is an important factor affecting V2V communication. Improving the routing selected strategy is of great significance to reduce the delay. Aiming at the routing selected strategy of V2V communication, a weight-based routing selected algorithm is proposed. Considering the position coordinates and channel capacity of vehicle nodes comprehensively, communication parameters that affect the transmission delay of V2V communication are determined. And a weight function is established. Then based on the requirements of low delay, according to the improved subjective and objective weighting method and simulation experiments, the weight factors in the weight function are obtained. Simulation experiments show that the weight-based routing selected algorithm has better delay and reliability performance, and the transmission delay is significantly lower than the Dijkstra and GPSR routing algorithm.
