摘要 该文基于大尺度路径损耗无线传播模型将高速公路场景中的车用自组织网络(VANET)建模为几何随机图,提出了VANET有效组网面积的概念,分析说明了VANET的准线性拓扑特点,并基于交通流理论关于自由流条件下的车头时距分布,推导得出了无线传输范围内至少存在k个邻居的概率计算方法。实验结果表明:该文提出的概率描述思想是一种适合计算高速公路场景中车辆网络节点度的有效方法。 Based on the large-scale path loss model for wireless communications,a Vehicular Ad hoc NETwork （VANET） in highway scenarios is modeled as a geometric random graph,the concept of effective networking area in VANET is proposed,the quasi-linear topological features of VANET is analyzed,the probability of nodes which have at least k neighbors located within its radio coverage is also derived,based on the assumption that the space headway under free flow conditions follows an approved traffic flow distribution. Experimental results demonstrate that the proposed algorithm,with the philosophy of thinking in probability,is an effective computational method on the node degree of a vehicular ad hoc network in highway scenarios.
