Abstract
In complex networks, there is a phenomenon of avalanche failures defined as cascading failures, caused by a few nodes randomly or deliberately and resulted in a significant number of nodes malfunction or the collapse of the entire network. To analyze the process of cascading failures, a method for simulation of cascading failures in complex networks based on cellular automata, a powerful calculation model in complex systems, is proposed in this paper. Through simulations in various scenarios, results show that cyber-attacks are more threatening than random failures. Also, random links in networks provide extra robustness when the scale of the network is large.
