摘    要:为了降低移动终端的能量消耗以及对基站空口资源的占用,IEEE 802.16e标准定义了休眠模式。针对计数器驱动的休眠工作模式与IEEE 802.16e标准不能较好兼容的局限,提出了改进的计数器驱动休眠算法,建立马尔可夫链模型分析其性能,推导出平均时延、平均功耗与计数器门限值等参数之间的内在关系,在此基础上给出了不同QoS要求的连接所对应的参数设置方案。

关 键 词:IEEE  802  16e  休眠模式  计数器驱动  功耗

Abstract:In order to save the energy consumption of the mobile stations and reduce the air interface resource utilization of serving base stations, the sleep mode is adopted in IEEE 802.16e standard. The counter-driven sleep mode algorithm has the advantage of simple and effectiveness, whereas it is difficult to be implemented in IEEE 802.16e system. To elimi-nate this limitation, the improved counter-driven sleep mode algorithm is proposed. The performance of the improved sleep method is evaluated based on the derivation of Markov’s analysis model. The relationship among the average energy consumption, average delivery latency and the threshold values of counters is investigated. The threshold parameters con-figuration scheme of counter for different QoS connection is presented.
Keywords:IEEE 802.16e  sleep mode  counter-driven  energy consumption
