A CONTROL POLICY OF INFORMATION FLOW BEHAVIOUR MODEL BASED ON NODE HETEROGENEITY

The development and improvement of Internet technology has made network information richer and more attractive. Users can access networks more easily and enjoy greater network services. While the Internet provides rich and convenient service, Internet networks also provide greater conditions now for the breeding and spreading of harmful information. The user is subject to information dissemination on the network, and the user's behaviour in information flow has a tremendous impact on information dissemination. In this paper, based on the heterogeneity of the nodes in a network, an information flow model is established, wherein the factors influencing a node's information flow behaviour are researched and categorized as factors internal and external to the node. The internal factor entails the autonomy of a node, which contains the degree of interest and the subjective judgment of the node. The external factors comprise the network structure, the location of the node, and the relationships among the nodes. Considering the issue of the spread of harmful information, a complex network model is built based on the information flow behaviour of the nodes, and a control policy to address harmful information is established.
