The Study of Information Dissemination Behavior in Online Social Network with Propagation Delay

In this paper, the information dissemination model involving propagation delay was studied. The effect of delay in the Social Network Service (SNS) was found by considering the theory of complex network and infectious disease dynamics. Also, the authors simulate the online social network information dissemination process and classify the different types of nodes. The simulation results show that: as the high connectivity of online social network, there is less threshold of information transmission in network; the propagation delay makes the threshold lower and the information is easier to be spread, but the propagation delay speeds down the information dissemination meanwhile it decreases the possibility of the information out breaking. This study posts a well understanding of the dissemination behavior with propagation delay in the SNS network, which is fundamental research on consensus.
