[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.
