Abstract

A mathematical model of dependence between two network layers, a dependent layer and an independent layer, is analyzed for its ability to capture cascading failures from one layer to another. A binary variable that captures whether or not a specific node is active is used to tie the two layers together. This methodology is applied to the interaction of the High Voltage Italian Electrical Transmission (HVIET) network and Italian high bandwidth internet network for research (GARR) network to test its viability and practicality. Vital nodes and node pairs in the HVIET network are identified using the model, and potential strategies for hardening the system are proposed. Further testing should evaluate different methods of linking the two layers.
