摘　　要：文章从能效测度入手,对已有的无线网络能效测度评价体系进行了讨论,并提出以碳排放量为标准和与网络负载相结合的能效测度模型。在能效测度模型的基础上,文章提出减少设备使用、无线资源调度、节点协作等一系列无线网络能效优化方法,并建议在无线网络协议架构中加入能效监控和能效评估模块。文章还对无线网络能效优化和评估方法中存在的技术挑战进行了展望。This paper discusses metrics and evaluation methods for energy efficiency in wireless networks. It is proposed that carbon emissions are the standard for measuring energy efficiency, and energy efficiency is evaluated according to different network loads. Using the metric model, several methods are available for reducing energy consumption, including decreasing equipment usage, radio resource scheduling, and node cooperation. Monitoring and evaluating energy efficiency should also be added to wireless network protocols as an extra module. Technical challenges associated with optimizing and evaluating energy efficiency are discussed in conclusion.
