Abstract
The continuous operation of modern society is dominated by interdependent networks, such as energy networks, communication networks, and traffic networks. As a result, the robustness of interdependent networks has become increasingly important in recent years. On the basis of past research, a no-feedback interdependent networks model is introduced. Compared with previous work, this model is more consistent with the characteristics of real interdependent systems. In addition, two types of failure modes, unilateral failure and bilateral failure, are defined. For each failure mode, the influence of coupling strength and dependency strength on the robustness of no-feedback interdependent networks was analyzed and discussed in relation to various giant component sizes. The simulation results indicated that the robustness of the no-feedback interdependent networks was inversely proportional to coupling strength and dependency strength, and the effect of coupling strength and dependency strength on the robustness was equivalent. These conclusions are beneficial for helping researchers and engineers to build more robust interdependent systems.
Highlights
The continuous well-adjusted operation of modern society is ubiquitous, it should not be taken for granted
Unlike previous studies that focused on the percolation process of no-feedback interdependent networks with different proportions of failure nodes, this paper focuses on the influence of dependency links on network robustness
We focuses on the collapse thresholds of no-feedback interdependent networks from two characteristics of dependency links, 4
Summary
The continuous well-adjusted operation of modern society is ubiquitous, it should not be taken for granted. The robustness of interdependent networks has been evaluated on the basis of three aspects: (1) the characteristics of subnetworks; (2) the property of dependency links; and (3) the failure mode of nodes. The influence of degree distribution on robustness has usually been studied based on different failure modes and coupling preference It was concluded in Reference [17] that a broader degree distribution of subnetworks increases the robustness of random coupled interdependent networks that are under random attack. Failure modes in previous studies that have been considered to inform the perspective of one subnetwork rather than the whole interdependent networks Such assumptions may lead to a misunderstanding of the operating characteristics of real interdependent systems.
