Relation existed in the social contact network can affect individuals' behaviors greatly. Considering the diversity of relation intimacy among network nodes, an epidemic propagation model is proposed by incorporating the link-breaking threshold, which is normally neglected in the rewiring strategy. The impact of rewiring strategy on the epidemic spreading in the weighted adaptive network is explored. The results show that the rewiring strategy cannot always control the epidemic prevalence, especially when the link-breaking threshold is low. Meanwhile, as well as strong links, weak links also play a significant role on epidemic spreading.
社会接触网络中存在的关系会极大地影响个体行为。考虑到网络节点间关系亲密度的多样性,通过纳入链路断裂阈值提出了一种流行病传播模型,该阈值在重连策略中通常被忽视。研究了重连策略对加权自适应网络中流行病传播的影响。结果表明,重连策略并非总能控制流行病的流行,尤其是当链路断裂阈值较低时。同时,与强连接一样,弱连接在流行病传播中也起着重要作用。
