Weight determination method for power communication heterogeneous network selection

Abstract

The invention discloses a weight determination method for power communication heterogeneous network selection, and the method comprises the steps: obtaining the subjective weight of a power communication heterogeneous network through employing an analytic hierarchy process, obtaining the objective weight of the power communication heterogeneous network through employing an improved entropy weightmethod, and searching a compromise between the two weights through employing a game theory. Therefore, the deviation between each weight and the optimal weight is minimized, and a relatively balancedand coordinated combined weight vector, namely the optimal weight combination weight selected by the power communication heterogeneous network, is obtained. An analytic hierarchy process is combined with an improved entropy weight method, professional judgment of experts is considered, and objectivity of a network selection result is guaranteed. Therefore, rationality and effectiveness of heterogeneous network access selection are ensured, wireless network resources are optimized, network capacity is improved, and power multi-service requirements can be met.

Description

technical field [0001] The invention relates to a power communication heterogeneous network method, which belongs to the technical field of communication. Background technique [0002] While the power wireless communication network is increasingly modernized and intelligent, its operating environment is also complex and diverse. A single communication system can no longer meet the overall needs of power services. Therefore, the existing power wireless communication adopts multiple systems, including 230MHz power wireless Private network, 1.8GHz power wireless private network, WLAN, WiMAX, and 5G public network and other different networks. In this heterogeneous multi-network mixed environment, network coverage in different regions is formed, and the advantages of various networks are complemented. . It is precisely because of the emergence of heterogeneous networks that power services face a new problem when accessing the network, that is, the problem of access selection of...

Problems solved by technology

However, there are corresponding disadvantages when using these two methods alone: ​​subjective empowerment only emphasizes the intention of experts, which makes the decision-making results more subjective and difficult to meet actual requirements; the process of objective empowerment no longer depends on the subjective judgment of experts themselves , but with the help of the mathematical relationship between the initial data to assign weights. Although there is a good mathematical theoretical basis, sometimes it cannot really reflect the importance of network attributes
