摘　　要：提出一种HMIPv6的改进协议PA-HMIPv6.PA-HMIPv6提供接入路由预选择机制,并在接入路由器和移动锚点引入转交地址池.接入路由器利用多重连接特性预先获取切换信息,提前为移动节点进行转交地址配置和重复地址检测操作,在移动节点切换之前完成地址池的初始化和信息更新工作,力求最大程度地减少切换时延.仿真实验表明,PA-HMIPv6协议能够有效缩短切换时延,减少切换过程中的数据包丢失率.We proposed an improved HMIPv6 protocol, called PA-HMIPv6 （ Prepe.red Allocation-HMIPv6 ）, which introduces a mech- anism of access route pre-choice and care-of address pool in access routers and mobile anchor points. Access routers obtain handover information in advance by multiple connections, which implement care-of address configuration and duplicate address detection opera- tion. The process of initialization and update of address pool, which completed before mobile node handover, seek to minimize the handover delay. The simulation results have demonstrated that PA-HMIPv6 protocol can effectively reduce the handover latency and packet loss rate.
