The network robustness against cascades is crucial for many networked systems. In the paper, we enhance the network robustness against cascades by rewiring edges of networks. Three edge-rewiring strategies are compared, including random rewiring strategy (RRS), assortative rewiring strategy (ARS), and low-polarization rewiring strategy (LPRS). The results show that ARS is more effective than RRS to...
How to defense the cascading failure and reduce the cost has become a hot topic in recent years. In this paper, we investigate the cascading failures caused by attacking on edges. A new fault-tolerant capacity model is proposed to resist the cascading failures triggered by an intentional removal of the edges with the lowest loads and a new measurement is put forward to quantify the effectiveness of...
In this paper, we examine the cascading failure on BA networks with scale-free property based on a load redistribution rule. Assuming that the robustness is quantified by the critical threshold Tc, at which a phase transition occurs from normal state to collapse, we find the strongest robustness against cascading failures in the case of alpha =1, which is a tunable parameter in our model. We further...
