Research Of Information Dissemination Based On Double Layer Network

Internet technology changes with each passing day,the rapid development of online social network provides a new way for people to exchange information.Virtual communication network built by social software,such as Facebook and Twitter,has become one of the important channels of information exchange,sharing feelings and personal opinions.From here we see that we are in a double layer network information dissemination mode,which consist of online social networks and offline social networks.With the number of online Internet users growth,and the change of information dissemination,the topological structure of network is becoming more and more complex.The research of double layer network has become a hot spot.Owing to the double layer network can accurately describe the information interaction behavior between online network and offline network in real world,the research on dynamic behavior of double layer network,which is of great significance to understand the phenomena.This paper starts with the topological structure of double layer network model,by studying the node characteristics and coupling mode of double layer network,a propagation dynamic model with the characteristic of double layer network is proposed.On this basis,the propagation process and immune strategy of them were studied.Main research contents are as follows.Firstly,constructing a new propagation dynamic model with double layer network propagation characteristics,by drawing unique inter layer coupling relation into traditional propagation model.From the point of view of network topology,we make a derivation of propagation threshold,the topological characteristics of nodes in double layer network system are also analyzed.Secondly,facing the problem of information propagation in double layer network,some structural parameters based on the double layer network,which affecting information propagation are analyzed: node degree,clustering and the interlayer connections.According to different influencing factors,simulate the propagation process of information on different coupled networks.Research shows that node degree and the interlayer connections have a positive impact on the speed of information propagation in double layer network,but clustering is just the opposite.Last,the control of harmful information on a double layer network is studied.Based on the information transmission model and topological parameters of a double-layer network,the propagation mechanism of information on double layer network is analyzed,and a node importance computing method is proposed.what's more,established a target immune strategy based on double layer network characteristics.Through simulation,the process of spreading the rumor after implementing the immunization strategy is realized,and the superiority of the immune strategy to the rumor control on the double layer network is verified.
