中文摘要：

车联网节点密度动态变化及节点快速移动,使得连通度成为影响其通信质量的重要因素。车辆以车队的形式在道路上行驶可以减少交通堵塞,同时降低燃油的消耗。研究了单车道和双车道的基于车队模型的车辆与车辆通信网络的连通度概率。研究和仿真结果表明,在有车队存在的VANETs中,网络的连通度概率比没有车队的网络有显著提高;同时,双车道网络的连通度概率比单车道网络也要高。该研究结果能够为未来的智能交通系统设计提供强有力的理论支持。

英文摘要：

Due to the dynamics of vehicle density and the fast movement of vehicles, connectivity is an important performance met-rics to indicate the communication quality of the Vehicular Ad Hoc Networks（ VANETs）. Grouping vehicles into platoons on the road can decrease traffic congestion, and reduce fuel consumption. This paper studies the connectivity probability in one- way and two-way platoon- based Vehicle- to- Vehicle（ V2V） communication networks. Analysis and simulation results show that the connectivity probability can be significantly improved when there are platoons in the network. Moreover, the connectivity probability in two- way network is higher than it in one- way network. These results can provide forceful theoretical support to the future Intelligent Trans-portation System（ ITS） design.
