摘　　要：随着移动互联网需求的不断增大,无线网络的能耗不断升高,而基站消耗了其中的大部分能源.针对当前LTE基站中资源过量供应导致的高能耗问题,本文提出了一种流量感知的节能资源分配算法.该算法针对具有不同流量特征的业务的服务质量需求,调整数据包的发送时机和发送数量,提高资源的使用效率.同时,本算法通过改变算法的参数来适配流量变化,可以在节能和性能之间取得较好的平衡.模拟实验的结果表明,本算法在基站负载40%以下时,以非延迟敏感业务的延迟性能为代价,能够以较少的资源获得与其他算法相似的吞吐量.With the increasing demand for mobile Intemet,the energy consumption in wireless network keeps rising and the base sta- tion con sum most of the energy. To improve of the energy consumption coursed by over-supply resources, a traffic-aware energy effi- cient resource allocation scheme has been proposed to optimize the PRB allocation process of LTE eNode. The time and number of sending packets of each flow with different quality of service has been optimized to improve the efficiency of resource. Meanwhile, the proposed scheme adapts traffic with different parameters and can achieve better tradeoff between energy efficiency and performance. The simulation results show that this scheme can achieve similar throughput to other algorithms with fewer resources at the expense of delay performance of non-delay sensitive flow when the traffic load is less than 40%.
