摘　　要：针对车载自组织网络在城市道路车流量大的情况,车辆在不同的路边基站之间频繁地进行上下文切换,从而导致IPv6的移动性支持协议切换时延过长的问题,提出了一种基于代理移动路由的快速切换方案。采用代理移动路由在3G/WiMAX通信域的切换触发其它802.11p通信域内的车辆发生切换的方法,来达到宏切换与微切换相结合的目的,从而实现批量式快速切换。分析结果表明,该方案较现有方案提高了切换效率,减小了切换时延。In vehicle ad hoc network（VANET）, vehicles need to switch from one road side unit（RSU） to another one frequently in urban traffic congestion, resulting in a long handoff delay of IPv6 mobility support protocol. A fast hand- over scheme based on proxy mobile router was proposed as a solution to the problem. The method that proxy mobile router＇s switching in 3G/WiMAX communication domain triggers the handover of other vehicles in 802. 11p communi- cation domain was proposed to achieve the purpose of combining macro switch with micro switch. And then, this method can achieve the goal of mass fast switching. The analysis shows that this scheme is superior to other existing programs in switching efficiency and handoff delay.
