摘要 为了提高电池供电的宽带无线接入设备的能量效率,采用马尔可夫分析模型的方法,研究IEEE 802.16e标准的休眠机制的工作行为,提出一种根据随机业务量的实时统计值而动态设置初始休眠窗口的新算法,分析功率损耗和数据包的平均时延与初始休眠窗口之间的关系,能够在整个休眠模式中节省较多的终端能量.仿真结果表明,新算法与标准比较能使终端功率损耗有明显的改善. To enhance the energy efficiency of broadband wireless access devices powered by battery, the operational behavior of sleep-mode in IEEE 802. 16e was investigated by means of Markov＇s analysis model. A new algorithm was presented to dynamically tune the initial sleep window, which was set according to real-time statistical value of the stochastic operational load, and the relationship of power consumption and mean time-delay of data packets to the initial sleep window was analyzed, so that the power for the terminals could be greatly saved in this sleep-mode on the whole. Simulation results showed that the algorithm proposed could achieve remarkable gain in terminal power consumption compared to the standard sleep mode.
