基于博弈论的社交网络谣言传播模型

Social Network Rumor Propagation Model Based on Evolutionary Game Theory

考虑到社交网络中谣言传播存在博弈现象,基于博弈论的方法建立适用于社交网络的谣言传播模型,该模型中将节点分为传播节点和健康节点,两类节点根据自身收益选择最优策略使自身利益最大化;并得到纳什均衡。对所提模型中各类节点收益进行分析,并用收益损失参数和额外收益参数来对节点收益进行量化分析。以MATLAB为实验平台,分别选取满足不同条件的参数进行分析。结果证明了所提模型的正确性。基于博弈论对谣言传播展开研究,有助于更加深入了解社交网络上谣言传播的内在机理,也为谣言的防控提供了理论参考。

Considering the game phenomenon of rumor spreading in social network,a social network rumor spreading model was build based on game theory,there are two kinds of nodes,one is the health node,the other one is the spread node. The nodes according to their own income to choose the most appropriate strategies to maximize their own interests,and get the Nash equilibrium finally. The benefits of various types of nodes was analyze,and used the appropriate parameters to describe the income of nodes in the evolution model. MATLAB is used as an experimental platform to test the parameters of different conditions,and the experimental results prove the correctness of the proposed model. The results is conducive to people from the perspective of game theory to further understand the spread of rumors on the social network mechanism,but also provides a theoretical reference for the prevention and control of rumors.
