Research on Robustness of Coupling Networks Based on Multi-subnet Composite Complex Network Model

Abstract

In order to solve the cascading failure problem of real networks, it is important to study the robustness of coupled networks. In this paper, a multi-subnet complex complex network model is used to build a cascading failure model on the coupled network. The influence of network size, adjustable parameters, and coupling factors on the robustness of the coupled network is mainly studied. Research shows that when both subnets are BA networks, the greater the contribution of the coupling relationship to the initial load of the nodes, and adopt heterogeneous coupling, networks will more robust.
