中文摘要： 面向我国车联网迅猛发展的重大战略需求，针对当前车联网协议/标准制定过程中对车联网连接性考虑不足，以及传统车联网连接性理论研究假设过于理想化的缺陷，本课题创新性地开展综合车流量、信道、基站间距、发射功率、网络最大跳数等多因素的车联网连接性理论研究，首先结合真实数据对车流量、3D信道进行建模研究，然后将所获取的车流量、信道模型纳入到对车联网连接性理论问题的分析与研究中，推导车联网连接概率在多因素综合影响下的上下限、通用表达式，找出多因素间的互动关系及置换规律,最后通过相应的软硬件仿真平台构建完成对所提核心理论的验证。本研究是对前人重要研究成果的继承与创新性拓展，将更加实际地反映现实情况中车联网实际组网及连接情况，可为车联网路由、MAC、组网、功控协议制定，以及后期车联网实际部署与管理奠定坚实的理论与技术基础，为推动我国车联网产业的发展贡献力量。

英文摘要： Connectivity probability is an important indicator of the Quality of Service (QoS) for Vehucular Networks (VANETs). It is also important to the design of networking, MAC, power control protocols and the operation of VANETs. However, little consideration on connectivity probability has been paid to protocol design and standard making process for VANETs. There are obvious drawbacks of inadequate assumptions of impacting factors to connectivity probability study in previous work. In this proposal, impacting factors of channel models, traffic flow models, deployment of roadside base stations, power of base stations and vehicles, maximum number of hops for relaying a packets, will be jointly considered. More importantly, in this proposal, modeling of traffic flows and 3D wireless channel according real data collected in Shanghai will be done at first. Then derivation of upper and lower bound of connectivity probability in VANETs will be carried on. The mutual relationship among the impacting factors will be thoroughly studied. Finally, the theoretical results will be validated vith a hardware online test platform and a software simulation platform. The completion of this proposal will contribute a lot on future deoloyment of VANET infrastructure.
