摘要
相依网络的鲁棒性是网络科学研究的重点问题之一,目前很多重要的工作都致力于这一问题的研究.基于此,系统研究了相依网络在几种蓄意攻击策略下的级联失效过程,发现了同时考虑两个网络中相依节点度的特性比考虑单侧网络节点度的特性的攻击策略更有效.研究成果不但有助于理解相依网络级联失效的过程,而且为找到相依网络的弱点并进行有效的保护和攻击提供了有益的提示.
The cascading failure processes of interdependent networks under several intentional attack strategies were studied. The simulation results show that comparing with the strategies that only consider the connectivity of nodes in one single network, the attack strategies will be more effective when the connectivity of nodes in both networks are taken into account simultaneously and the interdependent networks will seem more vulnerable. The study may be helpful for the understanding of cascading failures of interdependent networks, and can provide some helpful suggestions for the protection of interdependent networks under attacks.
