A trust evolution mechanism for mobile social networks based on Wright-Fisher

Abstract

With the development of mobile social networks, the trust problem of networks attracts more and more attentions. According to the existing problems of evolution model, this paper proposes a trust evolution mechanism for mobile social networks based on Wright-Fisher. Combining the evolutionary game theory and Wright-Fisher model, we establish the trust evolution model under white noise environment to analyze and predict the evolution trend of mobile social networks. In addition, in order to solve the free-riding problem in mobile social networks, this paper proposes an incentive strategy based on evolution theory. Through the experiments, we verify the effectiveness and adaptability of the proposed trust evolution mechanism. The proposed incentive strategy can inspire users to select trustful strategy, and improve the trust degree of the whole mobile social networks.
