Targeted Attack of Interdependent Networks Based on Asymmetric Dependency

Abstract

We expand the research to interdependent coupling networks based on asymmetric dependency. And then we focus on the robustness problem of interdependent networks under targeted attacks based on four different network combinations. The influences brought by tolerance coefficient of network nodes, coupling manner of interdependent networks and network removal proportion to network robustness are also analyzed. Research results show that under targeted attacks, network robustness depends on the size of attack scope. BA-BA interdependent networks perform better under large-scope attacks, and WS-WS interdependent networks perform better under small-scope attacks; based on a relatively small tolerance coefficient, the robustness of BA-BA interdependent networks tend to increase and then decrease with the increase of removal proportion.
