异构无线网络融合切换算法研究

摘要

异构无线网络融合和泛在化是未来宽带无线通信发展的必然趋势。文章首先概述了移动性管理；然后对切换进行了分类，讨论了各种切换策略；最后讨论了混合网络垂直切换策略，不同网络间的快速无缝切换是未来异构无线网络的一个极大挑战。%Abatract: The integration of heterogeneous wireless networks and ubiquitous networking is the inevitable trend of the development of broadband wireless communication in the future. The mobility management are discussed at ifrst. Then the handoff is classiifed and various handoff strategies are discussed. Finally, the vertical handoff strategies of hybrid network are discussed. Quick and seamless handover between different networks is a great challenge of heterogeneous wireless networks in the future.
