摘要/Abstract

摘要： IEEE802.16系统中引入休眠模式来减小终端的能量消耗以及对服务基站空口资源的占用。为了进一步有效提高终端的省电率,提出了一种基于业务量的自适应休眠机制。它能够根据终端当前的业务繁忙程度动态调整其工作模式,有效地避免了终端在普通模式与休眠模式之间频繁切换。通过建立该休眠机制的马尔科夫模型,分析了终端平均功率消耗、平均时延与计数器门限值之间的关系。仿真结果表明,与标准的指数增长算法相比,提出的休眠机制能量节省率至少可提高30%。

Abstract: The sleep mode is utilized to reduce the energy consumption of the mobile station and the resource occupation of the air interface of serving base station in IEEE802.16e network．In order to improve the efficiency of energy saving,a practical sleep mode based on traffic was proposed．User’s work mode can be determined according to the user’s active level and the frequent,so that user switch between wake mode and sleep mode can be reduced in the proposed scheme．Simulations were undertaken to verify the proposed scheme and analyze the effect of the threshold of counters on mean energy consumption and mean response time．The simulation results show that the proposed scheme can save at least 30% of energy compared with the standard method.
