| 摘 要： | 为减少移动站点(MS)的平均能耗(AEC)和其接收数据帧的平均等待时间(AWT),在分析IEEE802.16e规定的节能算法的基础上提出了一种休眠窗口的混合增长算法.该算法通过改变休眠窗口的增长速度,提高了移动站点节能综合性能.通过与IEEE802.16e规定的节能算法的对比分析和实验仿真验证了该算法的良好性能,并进一步考查了休眠模式中参数对算法性能的影响,有助于参数值的选取.结果表明:混合增长算法可以在获得更好节能特性的同时大大减少平均等待时间,尤其在到达率较低时,混合增长算法的平均能耗比指数增长算法降低15%～20%,平均等待时间减少50%～70%.

| Abstract: | Based on the analysis of exponential growth algorithm prescribed in IEEE 820.16e,a novel Hybrid Growth Algorithm(HGA)of sleep window was proposed to reduce the Average Energy Consumption(AEC)and the Average Waiting Time(AWT)of receiving the data frames of the Mobile Station(MS).The proposed algorithm promoted the comprehensive energy saving performances of MS by changing the growth rate of sleep window.The good performances of the proposed algorithm was validated via comparative analysis and experimental si... |
