针对目前车载移动容迟网络中的路边单元(RSU)部署问题，提出一种基于车流量的车载网络路边单元RSU部署方案，该方案通过对车载网中路口的车流量的统计行为进行分析，在城市重要交通枢纽和交叉路口部署路边单元RSU来进行辅助通信，从而有效提高车载移动网络的通信效率。根据北京和上海两地实际的车载移动数据，进一步对所提方案进行分析和评估。研究结果表明：在辅助车辆与车载之间的通信时，密集部署 RSU 可以创造连续的通信机会，从而有效提高网络性能。%Theroad side unit (RSU)deployment issueswere investigated. Based on the network traffic volume, the RSU into thenetworkwas deployed. The scheme analyzed the size of the statistical behavior of traffic flow through the junction in the vehicle network, and deployed the RSU to assist communication in the major transportation hub and intersections of the city, which can effectively improve the communication efficiency of the vehicle delay tolerant network.With thetwo actual vehicle traces of Beijing and Shanghai, analysis and evaluation of the proposed scheme werecarried out. The results demonstrate that the dense deployments of the RSU can create continuous communication opportunities in the communication between the auxiliary vehicle and the vehicle, and can effectively improve the network performance.
