中文摘要：

车载通信网络,由于其在智能交通和车载娱乐方面的广泛应用前景,受到了业界的广泛关注。车载通信具有车辆高速行驶、移动区域受限、网络拓扑变化快、通信过程频繁中断、以及要求私密性等特点。而基于WAVE的应用更容易部署,成本更低,更加符合商业模式,同时WAVE的标准化工作正在顺利进行中,所以关于WAVE的架构及通信过程成为了研究者们首先要关注的问题。

英文摘要：

Vehicular communication network is attracting more and more attentions,since its wide application prospect in Intelligent Transportation System (ITS) and vehicular entertainments.It has the characteristics as follows: high movement speed,constrained mobility,high dynamic topology,frequently disconnected network,privacy,and so on.Because the applications in WAVE are easier to be deployed,more cost-efficienct,and are more responsive to business models,the structure and communication process of WAVE become the...
