【摘要】：为更好地提升云计算环境下的信息资源服务,对云计算网络信息资源用户访问进行实时有效的规划。进行资源用户访问实时规划中,应对提取信息资源特征进行提取,计算出资源特征值的自相关函数,将每个云节点定义为平台的最小处理单元强度,但是传统方法通过对隐藏数据的目标位置和访问信道衰减参数进行同时估计,获取云计算网络的信息资源访问机制,但是不能准确获取信息资源特征和自相关函数,存在信息资源访问规划误差大的问题。提出一种二维KD树的云计算网络信息资源用户访问实时规划方法。上述方法先构建云计算网络的信息资源访问模型,提取信息资源特征,计算出资源特征值的自相关函数,将每个云节点定义为平台的最小处理单元强度,设计出非对称补偿滤波器对访问中干扰因素进行抑制,采用迭代方法对云计算网络的信息资源进行实时更新,有效地完成了云计算网络信息资源用户访问实时规划。仿真结果表明,所提方法有效地保障云计算网络的信息资源访问的实时性和准确性。
[Abstract]:In order to improve the information resource service in cloud computing environment, the user access of cloud computing network information resources is planned in real time and effectively.In the real-time planning of resource access, it is necessary to extract the feature of information resource, calculate the autocorrelation function of resource characteristic value, and define each cloud node as the minimum processing unit strength of the platform.However, the traditional methods obtain the information resource access mechanism of cloud computing network by simultaneously estimating the location of hidden data and the attenuation parameters of the access channel, but they can not accurately obtain the information resource features and autocorrelation functions.There is a problem of large error in information resource access planning.A two-dimensional KD tree based real-time planning method for user access to cloud computing network information resources is proposed.The above methods first construct the information resource access model of cloud computing network, extract the information resource features, calculate the autocorrelation function of the resource characteristic value, and define each cloud node as the minimum processing unit strength of the platform.An asymmetric compensation filter is designed to suppress the interference factors in the access, and the information resources of cloud computing network are updated in real time by iterative method, which effectively completes the real-time planning of user access to information resources in cloud computing networks.Simulation results show that the proposed method can effectively guarantee the real-time and accuracy of information resource access in cloud computing networks.
