摘要
In this paper, considering a control mechanism that uses an anti-rumor spread to combat a rumor spread, a novel susceptible-infected (SI) model is developed. By means of mean-field theory, the early stage propagation dynamics of the rumor and the anti-rumor on homogeneous networks and inhomogeneous networks are investigated, respectively. Theoretical analysis and simulation results show that, in both types of networks, as the immunity of the anti-rumor or the curing rate of infected nodes increase, the velocity of rumor spreading obviously decreases, which significantly reduces the probabilities of rumor outbreaks. Also, we find that shortening the time delay between the rumor starting and the anti-rumor starting can improve the control effect of rumor transmission. Our results may shed new light on the research of rumor control strategies.
