Abstract:

The basic mobile IP protocol is simple but only suitable for wide area and low speed networks. In this paper, we propose a novel micro-mobile IP handoff scheme, that is the packet loss avoidance handoff scheme. By using an additional cache at the base station and distinguishing packets with packet IDs, the proposed scheme minimizes the number of lost packets during handoff. Network architecture and detailed handoff procedures are given. We also analyze the cache size at the base station, the associated network load with the handoff procedure, and the handoff delay. The scheme is investigated by computer simulations. Simulation results show that the proposed scheme is suitable for environments with fast mobility and frequent handoff.

针对基本移动IP协议虽然简单但只适用于大范围、低速的情况, 提出了一种新的微观移动IP切换方法——避免分组丢失切换方法.该切换方法通过在基站处增加缓存以及利用IP分组的标识, 将切换过程中分组丢失减少至最小.并给出了该切换方法所适用的分层全IP网络结构及其切换过程, 对基站缓存的大小、切换带来的网络负荷、切换延时等也进行了分析.仿真和分析结果表明最小分组丢失切换方法适用于快速移动、频繁切换的环境.
