摘要
为了提高电池供电的宽带无线接入设备的能量效率,通过建立IEEE 802.16e休眠模式的马尔可夫分析模型,研究了休眠机制的能量效率,分析了功率损耗和数据包平均延时之间的关系,建议了一种动态算法来适应终端的随机化业务,理论分析和NS2仿真结果都表明建议的算法能在整个休眠模式中节省较多的终端能量。
To enhance energy efficiency ofbattery powered wireless access devices, the power efficiency for sleep operation is researched with established the Markov chain model of the sleep mode in IEEES02.16e, and the relationship is analyzed between the power consumption and the mean delay. Then, a dynamic algorithm is proposed to adapt randomization traffic of mobile station. Theoretical analysis and the NS2 simulations results show that the proposed algorithm can save more energy of the terminal.
