Role of Tie Strength in Information Dissemination in Mobile Social Networks

Abstract

In this paper, we propose a new model for information dissemination in mobile social networks, in which the infectious probability is defined as a function of the homogeneity and heterogeneity between nodes. Moreover, we investigate numerically the behavior of the model on a real scale-free social site with the exponent γ =1.08. We find that weak ties between nodes play an important role in information dissemination process. Specially, selecting weak ties preferentially can make information spread faster and wider, and the efficiency of diffusion will be greatly affected after removing them.
