用边缘去除策略抑制交通驱动的传染病传播

Suppressing traffic-driven epidemic spreading by edge-removal strategies

Han-Xin Yang, Zhi-Xi Wu, Bing-Hong Wang

摘要:

近年来,复杂网络上的流量动态与传染病传播之间的相互作用越来越受到人们的关注。然而,控制交通驱动的传染病传播仍然是一个具有挑战性的问题。在这份简报中,我们提出了一种方法,通过适当地删除网络中的一些边缘来抑制流量驱动的流行病爆发。我们发现,可以通过有针对性地切割具有最大算法介数的大度节点或边之间的链接来提高流行阈值。相反,通过随机边缘去除,将降低流行阈值。这些发现是强大的交通流量条件,网络结构和路由策略。此外,我们发现,目标边缘的关闭可以有效地释放通过大度节点的流量负载,使这些节点的感染概率相对较低。

英文摘要:

The interplay between traffic dynamics and epidemic spreading on complex networks has received increasing attention in recent years. However, the control of traffic-driven epidemic spreading remains to be a challenging problem. In this Brief Report, we propose a method to suppress traffic-driven epidemic outbreak by properly removing some edges in a network. We find that the epidemic threshold can be enhanced by the targeted cutting of links among large-degree nodes or edges with the largest algorithmic betweeness. In contrast, the epidemic threshold will be reduced by the random edge removal. These findings are robust with respect to traffic-flow conditions, network structures and routing strategies. Moreover, we find that the shutdown of targeted edges can effectively release traffic load passing through large-degree nodes, rendering a relatively low probability of infection to these nodes.
