考虑好奇心理机制的动态复杂网络谣言传播研究

Rumor spreading on dynamic complex networks with curious psychological mechanism

考虑好奇心理机制的影响,提出一种动态复杂网络演化模型,基于数值仿真研究谣言的传播动力学行为。研究表明,好奇心理机制的存在降低了网络的传播临界值,增大了谣言的传播速率以及最终的传播程度。研究还发现,动态连接概率对谣言传播机理产生了较大影响,而附加感染率产生的影响可以忽略不计。此外,在好奇心理机制的作用下,谣言在网络中的传播时间明显缩短,同时给出有效防控谣言传播的合理化建议。

Considering the influence of curious psychological mechanism,this paper proposes a dynamic complex network evolution model. Based on this model,the dynamical behaviors of rumor spreading are investigated by using the numerical simulations. The research shows that the existence of the curious psychological mechanism reduces the propagation critical thresholds of the networks,increases the spreading velocity and the final propagation extent of rumors. It is also found that the dynamic connection probability has a great influence on the propagation mechanism of rumors,but the effect of the additional infection rate is negligible. In addition,under the influence of the curious psychological mechanism,the rumor spreading time on the networks is obviously shortened,and the reasonable suggestions for effective prevention and control of rumor spreading are given.
