摘要:

以往相依网络的级联失效研究都基于相同子网络级联机制的假设下进行分析,在借鉴前人研究的基础上,利用负载能力模型提出基于不同子网络级联机制的相级联模型,并分析不同攻击策略对相依网络鲁棒性的影响。通过针对相依ER随机网络和相依无标度网络的攻击策略模拟仿真,对比不同攻击策略的效果,从而发现相依网络拓扑结构要素对不同攻击策略的影响。同时,通过对比同一攻击策略下的不同级联失效机制的效果,发现了级联失效机制的对称性对相依网络鲁棒性造成的影响。

Abstract:

Previous researches on cascading failure of interdependent networks are based on the same subnet cascade mechanism. Based on the previous studies, the loadcapacity model is used to propose a cascading model based on different subnet cascade mechanism. The impact of different attack strategies on the robustness of interdependent network is analyzed. By simulating interdependent ER random networks and interdependent scalefree networks, the effect of different attack strategies is compared, and the influence of topology elements on different tactics is found. In addition, by analyzing the results of different cascading failure mechanisms under the same attack strategy, it is discovered that the symmetry of the cascading failure mechanism greatly affects the robustness of interdependent network.
