摘　　要：提出了一种面向路侧单元的自组网路由协议.该协议采用树形拓扑结构,路网分为若干交通控制子区,各子区设有交通控制子中心,网络采用无线或有线方式与控制总中心相连,各子区内以交通控制子中心作为根节点,路侧单元作为路由子节点,通过自组网路由协议,构建路侧单元自组网络.仿真实验结果证明,借助路侧单元自组网络,实现相互车路通信和车车通信,很大程度上改善了车载自组网的信息发布与数据聚合.A routing protocol in ad hoc networks based on roadside unit（ RSU） is proposed. The protocol uses the tree topology structure and the road network is divided into several traffic control area（ TCA） which used the wireless or wired mode to connect the control center. It made a traffic control center（ TCC） as a root node and RSU as a routing node in each TCA and it constructs a dynamic network of RSUs by this protocol. The experimental simulation shows that,by using the dynamic network of RSUs,this protocol can realize communications of vehicle to road and vehicle to vehicle,and it can improve the information publishing and the data aggregation of vehicular in ad hoc networks（ VANETs） greatly.
