自适应路由策略抑制流量驱动的传染病传播

Suppressing traffic-driven epidemic spreading by adaptive routing strategy

Han-Xin Yang, Zhen Wang

摘要:

近年来,流量驱动的传染病传播路由策略的设计受到越来越多的关注。在本文中,我们提出了一种自适应路由策略,通过一个可调的参数$h$,将拓扑距离与当地的流行病信息。在无拥塞的情况下,存在一个最优的路由参数$h$值,导致最大的流行阈值。这意味着与静态最短路径路由方案相比,自适应路由可以更有效地控制传染病传播。此外,我们还发现,在节点传输容量有限的情况下,最优的$h$值可以极大地缓解业务拥塞。我们希望我们的工作提供了新的见解动态路由交通驱动的传染病传播的影响。

英文摘要:

The design of routing strategies for traffic-driven epidemic spreading has received increasing attention in recent years. In this paper, we propose an adaptive routing strategy that incorporates topological distance with local epidemic information through a tunable parameter $h$. In the case where the traffic is free of congestion, there exists an optimal value of routing parameter $h$, leading to the maximal epidemic threshold. This means that epidemic spreading can be more effectively controlled by adaptive routing, compared to that of the static shortest path routing scheme. Besides, we find that the optimal value of $h$ can greatly relieve the traffic congestion in the case of finite node-delivering capacity. We expect our work to provide new insights into the effects of dynamic routings on traffic-driven epidemic spreading.
