摘　　要：车载网络信息技术的高速发展对移动过程中信息交换提出新的挑战,针对域内及域间频繁切换所产生的绑定更新信令开销大、数据包发送时间延长的问题,提出了一种新的车载网络移动协议,该协议通过改进的HMIPv6指针传递算法(EPF-HMIPv6),对切换过程中的数据发送路由进行优化.仿真实验结果表明,该算法在绑定更新开销、数据包发送开销等方面均优于现有的车载网络移动管理算法.The frequent inter-domain or intra-domain movement of vehicles in vehicular networks may lead to large binding update costs and packet delivery costs. In order to solve this problem, an improved pointer for- warding scheme（EPF-HMIPv6） was developed in thwas paper. The scheme was based on the existing pointer forwarding scheme in cellular networks, and the routing of packets was optimized. To evaluate the performance of the proposed scheme, Analytical expression we were derived for binding update cost, signaling overhead caused by HMIPv6 and EPF-HMIPv6 handovers. The simulation results showed that the proposed scheme was better than the existing mobility management protocols in vehicular networks.
