Abstract: In recent years, the robustness of edge-coupled interdependent networks has been investigated and has attracted much attention from researchers in different fields. Currently, most research on edge-coupled interdependent networks focuses on two-layer systems with simpler RR or ER topologies. However, studies on multilayer edge-coupled interdependent Scale-Free networks are scarce. In this paper, we propose a multilayer edge-coupled interdependent SF network model and study the cascading fault propagation mechanism caused by attacking a small number of edges. The effect of coupling strength on the robustness of multilayer edge-coupled interdependent Scale-Free networks is also considered. Based on the fact that self-consistent probability theory can greatly simplify the mathematical analysis of such systems, the paper provides a theoretical analysis of the phase transition behavior. The research results help to deepen the understanding of the robustness of multilayer Scale-Free interdependent networks and provide some valuable suggestions for the protection and improvement of complex network systems.
