摘　　要：对网络通信能量资源进行调度优化的过程中,由于资源的多样性,异构性,自治性的特点,使得执行所需能量与时间容易出现关联性低的情况,传统的资源调度算法,能量消耗与时间消耗值由于低关联性的干扰,取值不明确,导致资源利用率低,无法有效实现资源调度。提出一种基于时间尺度分析的网络通信能量资源调度算法,分析网络通信能量资源调度问题描述,给出了时间消耗子模型。引入一个代价函数,用于描述任务由资源执行所需的能量消耗与时间消耗的总和。通过MQoS向量可对一个服务资源的物质属性与社会属性进行描述,实现云计算网络空间资源的描述。对资源向量矩阵进行归一化处理,获取规范化矩阵。对各维QoS指标设置权值,依据云计算用户服务需求的异构性,进一步细分成欧氏距离算法。仿真结果表明,所提算法具有很高的调度优越性。A scheduling algorithm for network communication energy resources is presented based on a time scale analysis. The scheduling problem of network communication energy resources is described, a time consumption model is given. A cost function is introduced, which is used to describe the sum of the energy consumption and time con- sumption for performing the task. The material attribute and social attribute for a service resource is described by MQoS vector, and then the cloud computing network resource space is described. The vector matrix of resources is normalized, and the canonical matrix is obtained. The weights of each dimension QoS indicators are set. According to the heterogeneity of service requirements for cloud computing users, the Euclidean distance algorithm is further subdi- vided. The simulation results show that the proposed algorithm has high scheduling performance.
