Wireless access to Internet services will become typical, rather than the exception as it is today. Such a vision presents
great demands on mobile networks. Mobile IP represents a simple and scalable global mobility solution but lacks the support
for fast handoff control and paging found in cellular telephony networks. In contrast, second- and third-generation cellular
systems offer seamless mobility support but are built on complex and costly connection-oriented networking infrastructure
that lacks the inherent flexibility, robustness, and scalability found in IP networks. This paper presents an overview and
performance comparison of two of the main micro-mobility protocols, namely Cellular IP and Hierarchical Mobile IP with regards
to the handoff process for UDP applications. The differences in the handoff quality of the two protocols are small and can
be traced to design choices within the typical model. There are however significant differences regarding the processing requirement,
routing efficiency and parameters relating to implementation and deployment. 相似文献

移动IP是IETF支持因特网上主机透明移动性的一种参考协议,在向全IP蜂窝网络演进的过程中,移动IP提供了域之间移动的解决方案,即宏移动性管理,但它不能解决在蜂窝网内移动时所遇到的问题。移动IP的种种缺陷导致了近年来各种微移动性管理协议的出现,分析了几种典型的IP层微移动性协议,在此基础上提出了对设计新的微移动性协议的几点考虑。 相似文献
