摘要
IP微移动是一种能够在移动过程中有效改善移动节点通信质量的移动性管理方式,其核心部分为切换管理。该文首先分析了IP微移动的切换过程,并从网络层切换和链路层切换的关系及其交互性的新视角提出了切换管理的分类方法,详细分析和研究了目前典型的IP微移动协议的特点和存在的问题,并给出对这些协议的性能比较,最后讨论了IP微移动切换管理的未来研究方向。
IP micro-mobility is one of the mobility management methods that can improve the communication quality during movement of mobile nodes. Handoff management is its key technology. In this paper, a comprehensive survey on IP micro-mobility handoff management is given. A new classification of handoff manageraent, from the viewpoint of relationship and interaction between network-level handoff and data-link-level handoff, is introduced. Further, the characteristics and problems of some representative IP micro-mobility handoff protocols are analyzed in detail, and the comparison results are given also. Finally, future research directions of IP micro-mobility handoff management are discussed.
