IEEE802．16e中的节能机制研究

IEEE802．16e技术以其高带宽、强移动性正成为宽带无线接入技术的焦点，与此同时，移动用户站在移动中如何去节省能量、延长工作时间，也日益被人们所关注。文章研究了IEEE802．16e无线城域网中的节能机制问题。首先介绍了IEEE802．16e下移动用户站的睡眠模式，然后对该睡眠模式建立分析模型，并根据模型进行了仿真，最后对仿真结果进行了总结。

The Study of Energy Saving Scheme in IEEE 802.16e

For its high bandwidth and strong mobility the technology of IEEE 802.16e is becoming the focus of broadband wireless access technology.At the same time,how to make MS(Mobile Station) save energy and extend work time is cared about.In this paper,the problem of saving energy mechanism in the IEEE 802.16e WMAN(Wireless Metropolitan Area Network) is analyzed.Firstly MS sleep-mode in the IEEE 802.16e is introduced.Secondly,the sleep-mode scheme is modeled and simulated.Finally,the results of the simulation are ...
