【摘要】 路边单元(Road-Side Unit,RSU)是车辆自组织网络(VehicularAd Hoc Networks,VENET)的重要组成部分,它能为车辆和后台管理控制中心提供各种类型的服务,安全服务是其中的重要应用之一。本文首先探讨安全应用下RSU在VENET中的联网方式,分析了在这种联网方式下的路边单元与后台管控中心之间在某一时段通信延时过大的问题。然后对已有的RSU联网方式进行改进并提出了一种寻找代理RSU的路由算法。这种算法能够解决上述问题所导致的某一时段内消息传输的非实时性。更多还原

【Abstract】 Road-Side Unit(RSU) is an important component of Vehicular Ad Hoc Networks(VANET).It can provide many kinds of services for vehicles and control center,in which safety service is the most important application.This paper investigates the networking method of RSU in the VANET for safety service,and then analyzes the problem that the time delay between one of RSUs and the control center is too large in a period.Based on the analysis,a routing algorithm called Finding Proxy RSU is proposed.The routing algorithm can inhibit the non-realtime message transmission which is caused by that problem.更多还原
