摘　　要：分析了AdHoc网络接入Internet时基于移动IPv6切换管理方式的不足,提出了支持微移动性的切换机制,通过新增本地代理和外地代理,将家乡代理的部分管理功能下放到这两个代理中,从而实现了微移动对网络的屏蔽。分析表明,在域间切换概率较小的情况下,新的切换机制的平均切换时间大大缩短,在一定条件下与先验式切换协议相比,切换时间可以缩短近50%。This paper firstly analyzed the drawbacks of handoff in Ad Hoc networks being integrated to Internet based on mobile IPv6. Local Agent and foreign Agent were introduced into MIPv6 in the handoff mechanism which supported intra mobility, and part of the mobility management ability of the home Agent was transferred to local Agent and foreign Agent, then the intra mobility could be shielded from the home Agent and correspondent node. The results show that the handoff time decreases greatly, when the inter-handoff probability is low, the average handoff time can be cut to 50% of the proactive handoff time under certain condition.
