异构无线网络中辅助切换决策的移动分类策略

With the rapid development of wireless technologies, various kinds of networks are deployed with different attributes. Heterogeneous networks will satisfy diverse application requirements for mobile users, and offer communication continuity. However, heterogeneous wireless networks impose challenges about cooperation of different access technologies. Efficient handoff is one important solution to address these challenges. In this paper, we proposed a motion classification strategy (MCS) to assist handoff decision. Based on positioning information data such as location coordinates, moving velocity and direction, MCS can predict the next location for a mobile node (MN) in motion, distinguish different motion scenarios, and assist handoff decision to improve communication performances. The analysis results demonstrate the excellent performance of MCS assisted handoff decision mechanism.
