Heterogeneous network multi-attribute decision-making method based on network analytic hierarchy process

Abstract

The invention discloses a heterogeneous network multi-attribute decision-making method based on a network analytic hierarchy process. According to the method, when computing network attributes weight, attributive interaction and feedback in a dynamic network are considered, influence on network selection of a target network is also considered, physical truths for decision problems of a heterogeneous network are well fit, and a low-delay and low-quivering network can be selected under a real-time voice service. Concrete steps comprise that weight is firstly calculated; attributive factors affecting the network selection and the target network are divided into a functional group, a cost group and a scheme group; mutual relation between intra-groups and between-group elements and mutual relation between groups are set up; judgment matrixes of pairwise comparison according to the analytic hierarchy process are set up, feature vectors are obtained, submatrixes are formed, and all the submatrixes form a non-weighted hypermatrix, and an ultimate hypermatrix and ANP weight are obtained through weighting and exponentiation operating of the hypermatrix; and then the ANP weight and normalization network parameters obtain network power functional values, the network power functional values are sorted, and the largest utility value is selected to serve as the target network.

Description

technical field [0001] The invention relates to a heterogeneous network multi-attribute decision-making method based on the network analysis method ANP (heterogeneous network), which belongs to the technical field of communication. Background technique [0002] With the development of wireless communication technology, various wireless technologies will coexist in the future, and heterogeneous networks are the development trend of next-generation wireless networks. The third-generation mobile communication system envisaged in the past is a unified technology and unified management network composed of some advanced wireless technologies, while 4G is a combination of various types of wireless access technologies working together on an IP platform. How to make a reasonable selection of the existing network is an important issue in current research. In the heterogeneous converged network environment, the heterogeneity and difference of the network are relatively large. In the n...

However, in actual decision-making problems, some indicators often have mutual influence.

[0007] 3. There is only a top-down influence between two adjacent layers between each layer, without considering the reaction of the lower layer to the upper layer

[0008] However, the three assumptions deviate from some practical decision-making problems, and the interaction and feedback of various elements in the complex dynamic system are not considered theoretically. Although the subjective weight is obtained qualitatively and quantitatively, it is not the result that is most in line with the real situation. , it is necessary to improve
