中文摘要：

针对全球微波互联接入（Wi MAX）网络节能算法中因移动节点（MS）的信道质量差别引起的空闲状态而浪费能量这一不足,依据IEEE 802.16e标准第Ⅰ类节能模型给出了MS服务质量目标的平均能耗（AEC）形式化描述,并提出一种基于信道质量均衡的避免终端空闲状态虚拟突发的节能调度（IAVB）算法。该算法采用将空闲状态阈值和基于信道质量的状况选择主移动终端相结合的策略,并完善了虚拟突发的结束条件,很好地避免了因未正确结束虚拟突发而导致的终端空闲状态造成的能量浪费问题。仿真实验表明,在节能方面IAVB算法比最长虚拟突发优先（LVBF）算法性能平均提高了15%。实验结果表明该算法减少了终端的空闲状态,有效地降低了终端能耗,提高了Wi MAX网络的资源利用率。

英文摘要：

To overcome the shortcoming in the energy-saving algorithm of WiMAX networks that energy is unnecessarily wasted by idle mobile stations because of channel quality difference, according to the energy-saving class I of the IEEE 802.16e standard, the formalization of Average Energy Consumption （AEC） was given for Mobile Station （MS） Quality of Service （QoS）, and an algorithm of Idle-state Avoidance and Virtual Burst （IAVB） based on channel quality balancing was proposed. In this algorithm, the strategy combining a threshold of idle-state with choosing the main mobile terminal based on channel quality balancing was adopted, and the end condition of virtual-burst was perfected to avoid the energy waste between idle-state nodes when the virtual-burst did not end properly. The simulation results show that the energy saving performance of IAVB algorithm is 15% higher than that of the Longest Virtual Burst First （LVBF） algorithm. The experimental results show that the proposed algorithm can control the energy consumption of idle-state and improve the resource utilization efficiency of the WiMAX network.
