中文摘要: 车辆网络作为道路上车辆间、车辆与固定接入点之间相互通信组成的开放移动自组织网络,正日益受到国内外研究者和产业界的关注。但是作为车辆网络的重要应用基础问题:其网络容量到底如何,网络传输性能能否支撑大规模的应用呢?一直没有深入、系统的解决。为此本项目针对车辆网络道路拓扑、移动、混合、多信道、支持定向天线的特点,求解其网络容量的理论结果。具体研究道路拓扑约束带来的影响因子,建立基于定向天线的非移动混合多信道车辆网络容量分析模型;然后分析研究车辆节点移动模型,及其对网络容量的影响增益,进一步揭示在车辆移动状态下的容量变化趋势;在此基础上,研究综合各方面参量的车辆网络容量分析模型框架,建立最优传输调度和路由机制,获取网络容量的上下界值。

英文摘要: Vehicle networks as the Open Mobile self-organizing networks with communications between vehicles on the road and with fixed access points beside road are increasingly subject to domestic and international researchers and industry attention. But as its basic problem of applications: What is the throughput capacity, and can the network transmission performance support the large-scale application? There has been no in-depth, the system solution. Considering its characteristics road topology, mobile, mixed, multi-channel, support the directional antenna, the theoretical results of its network capacity is solved. Specific studies include the impact factor of road topology constraints, the establishment of hybrid multi-channel non-mobile vehicle network capacity analysis model based on directional antenna; analysis of the Vehicle node mobility model, and its impact on network capacity gain; further reveal the capacity trends under movement state of vehicles ; on this basis, Taking all parameters of the vehicle network capacity as analysis model framework, the optimal transmission scheduling and routing mechanisms are constructed, and the upper and lower bounds of the network capacity are then obtained.
