摘　　要：针对云数据储存能量消耗大的问题,提出基于贪婪算法的云计算数据块节能存储方法。建立具有用户访问层、核心服务层和服务管理层的云计算架构,了解数据块产生过程和储存环境;将物理机利用率、能源消耗量和主机储存能力作为节能储存的约束条件,将待储存的数据块封装为虚拟机,利用贪婪算法描述虚拟机部署问题,构建贪婪算法下虚拟机分配环境;计算单个物理机和整个数据中心的数据块储存能力和资源请求能力,综合考虑虚拟机分配的相关向量,运算数据储存时的能量消耗;以总体能量最小为目标函数,将虚拟机分为主模块与备用模块,通过设置虚拟机状态转换规则来减少储存开销,实现节能储存。实验结果表明,上述方法在数据储存过程中能够有效减少服务器开启数量,节省储存功率,达到节能目的。Human-computer interaction is the process of information exchange between people and computers or other external devices.In the process of human-computer interaction,the complexity and instability of network can directly affect the perception effect of visual objects.Therefore,a method of sensing visual objects in the process of human-computer interaction is proposed based on virtual reality.Firstly,virtual reality technology was used to build a safe environment for human-computer interaction network,and then 2D image of visual object was captured in this environment.Secondly,Gabor wavelet transform method was used to extract the feature vector of visual object.Thirdly,least square support vector machine was used to construct a model of sensing visual object in human-computer interaction,and then relevant parameters of the model were determined by particle swarm optimization.Finally,the extracted target feature vectors were input into the model,thus completing the perception of visual objects.Experimental results prove that the average perceptive accuracy of the proposed method is between 95%and 100%,which is higher than the results of the other methods.In addition,its perception speed and perception effect are also better than others.
