无线异构网络的垂直切换判决算法

传统上的水平切换处理方法已经应用在同一接入技术的网络中（如无线蜂窝网络）。随着多种异构无线网络的出现,下一代网络必须支持垂直切换技术以保证用户从一个网络切换到内一个网络时仍然保持连接,垂直切换作为多网融合的基础,受到了学术界和工业界的广泛关注。对使用层次分析法进行垂直切换技术的工作原理及应用环境进行了分析,提出同时使用多种切换技术以解决不同环境下的切换问题。

An Algorithm for Vertical Handoff in Heterogeneous Wireless Networks

The taditional the handoff process has been ueed in aming the wireless networks with same access technology(e.g.,cellular network).With the emergence of various heterogeneous wireless access networks,the next generation wireless networks must support the vertical handoff mechanism in which users could maintain the connections when switched from one network to another(e.g.,from IEEE 802.11b to CDMA).Vertical handoff is the basic requirement for convergence of different access technologies and receives much a...
