摘要:

通过考虑用户移动性和QoS要求,设计了移动无线因特网中的一种扇形资源弹性预约机制,包括运动预测、资源预约和QoS协商。该机制还考虑了移动用户频繁切换的解决方法  。仿真研究表明,扇形资源弹性预约机制可以有效地保证移动用户的QoS。

关键词: 扇形资源预约 运动预测 QoS协商 移动无线因特网

Abstract:

With the users' mobility characteristics and QoS (Quality of Service) requirements being considered, a fanshaped flexible resource reservation mech  anism, including motion prediction, resource reservation and QoS negotiation schemes is presented. It also includes the solutions to the frequent handof  f problems with mobile users. Simulation results show that the mechanism effectively ensures the QoS of mobile users.

Key words: (fan-shaped resource reservation motion prediction QoS negotiation, mobile wireless Internet)
