Cascading Failures in a New Multi-coupling-links Three-dimensional Coupled Networks Based on Coupled Map Lattices Model

摘要

The paper presented a new multi-coupling-links scale-free coupled networks model based on the existing scale-free network model. More precisely, we investigated the cascading failures of multi-coupling-links three-dimensional coupled networks based on coupled map lattices model. And through Matlab simulation, this paper detailedly studied the cascading failure under different attack strategies, different coupling strength and different network's scale. The results indicate that the deliberate attack has a faster transmission speed than the random attack under the same perturbation amplitude; the greater coupling strength of the network, the more likely to occur global failure; the coupled networks performs more robust to resist cascading failures if each sub-network possess a larger average scale; and under the deliberate attack, the network in a isolated state is more vulnerable than in a coupled state.
