摘　　要：针对车辆传感器网络的特点,提出一种基于分簇定向扩散与智能路由的泛在互联车辆传感器网络体系结构。该体系结构充分利用车辆传感器网络节点的多途径联网功能以及自组网能力,利用分簇定向扩散机制形成无线自组网与传统网络相结合的混合逻辑拓扑结构HLT-C&DD,通过节点的智能路由功能为网络中的数据汇聚提供智能分流途径。理论分析和仿真结果表明,该体系结构能提高泛在互联车辆传感器网络的综合性能。Aiming at the characteristics of vehicular sensor network, an architecture for ubiquitous-inter- connection vehicular sensor networks based on clustering directed diffusion and intelligent routing is pro- posed. With this architecture, the multi-channel networking capability and Ad hoe network capability of road-side node or vehicle node could be in full use, by clustering directed diffusion mechanism （HLT- C＆DD）, the hybrid logical topology of traditional network and wireless ad hoe network is formed, and the intelligent shunt pathway for network data aggregation is provided through intelligent routing function of the nodes. Theoretical analysis and simulation results show that this architecture could improve the comprehen- sive performance of ubiquitous-intereonnection vehicular sensor network.
