摘要:

目前对于多层网络上病毒传播问题的研究都在静态网络上进行,然而绝大多数的实际网络系统都具有时变特性,对动态多层网络中病毒传播问题的研究尚不深入。研究了动态网络与静态网络相结合的双层网络模型下病毒和信息相互作用的病毒传播行为学,发现信息层网络结构、路由策略以及信息传播概率、病毒抑制度对病毒传播阈值有显著影响。当信息完全抑制病毒时,自我意识率可以有效地控制病毒感染规模。通过调整病毒层动态网络节点移动速度和接触半径,研究了病毒传播与交通动态之间的相互作用,发现随着节点移动速度的增加,病毒传播阈值减小,但随着接触半径的增加,会有效抑制病毒的爆发。

关键词: 多层网络, 动态网络, 交通驱动, 病毒传播, 路由策略

Abstract:

Current studies on epidemic spreading in multilayer networks are conducted on static networks. However, most of the real-world networks exhibit temporal properties, and extensive research on epidemic spreading in dynamic multilayer networks is not yet done. This work investigates the epidemic spreading behavior of epidemic and information interactions in a two-layer network model combining dynamic and static networks. It was found that the network structure, routing strategy, information transmission probability, and degree of epidemic suppression had a significant impact on the threshold of epidemic spreading. When information completely suppresses the epidemic, the self-awareness rate can effectively control the scale of the epidemic infection. This paper also studies the interaction between epidemic spreading and traffic dynamics by adjusting the node movement speed and contact radius of the dynamic network of thee pidemic layer and finds that the epidemic spreading threshold decreases as the node movement speed increases, whereas the outbreak of the epidemic is effectively suppressed as the contact radius increases.

Key words: multilayer networks, dynamic networks, traffic-driven, epidemic spreading, routing strategy
