| Abstract: | In the vehicle ad hoc networks, user nodes transmit information to each other by establishing a connection between relay nodes and sink nodes, but the end-to-end throughput in the connection is always lower. To solve this problem, the method of choosing the optimal relay node based on the stability is proposed. Modeling the position of vehicles,then combining the factor of stability and selecting the best relay node, the throughput would be improved as soon as the nodes are selected by calculating.Finally, the simulation experiment is carried out, and the result shows that themethod is correct and effective, and this method improves the throughput between the nodes. |
