Cascading failure in Watts–Strogatz small-world networks

Xia, Yongxiang; Fan, Jin; Hill, David - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 6, pp. 1281-1285

In this paper, we study the cascading failure in Watts–Strogatz small-world networks. We find that this network model has a heterogeneous betweenness distribution, although its degree distribution is homogeneous. Further study shows that this small-world network is robust to random attack but...

Optimizing complex networks for resilience against cascading failure

Ash, J.; Newth, D. - In: Physica A: Statistical Mechanics and its Applications 380 (2007) C, pp. 673-683

Our modern society has come to depend on large-scale infrastructure networks to deliver resources to our homes and businesses in an efficient manner. Over the past 10years there have been numerous examples where a local disturbance has lead to the global failure of systems. In this paper, we use...

Equilibrium games in networks

Li, Angsheng; Zhang, Xiaohui; Pan, Yicheng; Peng, Pan - In: Physica A: Statistical Mechanics and its Applications 416 (2014) C, pp. 49-60

It seems a universal phenomenon of networks that the attacks on a small number of nodes by an adversary player Alice may generate a global cascading failure of the networks. It has been shown (Li et al., 2013) that classic scale-free networks (Barabási and Albert, 1999, Barabási, 2009) are...
