中文摘要：

提出了一种基于车栽自组织网络的车辆实时信息查询模式．在该模式下，实时交通及设施服务信息和用户查询都采用自组织网络传染病路由的方式进行数据传榆和发布，只有当查询和实时报告信息在某个节点匹配后，为了节省查询时间，将查询结果信息通过基础设施网络返回查询节点．针对该车辆实时信息查询模式建立了系统模型，对系统查询机制和延时进行了理论分析和推导，并在s11uwl，swANs环境下验证了推导结论，为系统的参数设置和优化提供了理论依据。

英文摘要：

A vehicular real-time information query mode based on vehicular Ad hoe network （VANET） is proposed in this paper. The real-time traffic information report, facilities service information report, user queries, etc., are disseminated via epidemic routing in the system. Only after a query and a report matched at a node, the report will be returned to the query node via infrastructure network to speed up the query efficiency. The system model is analyzed and the system delay is theoretically deduced. Furthermore, the derived conclusions are validated in STRAW/SWANS simulator, which provide a theoretical basis for parameters setting and optimization for the VANET system.
