摘要: 考虑到现实网络中由于一些保护措施的存在,使得一些超负荷的边并不会立即从网络中移除,提出了超负荷边崩溃概率的机制,并构建了一个超负荷边带有崩溃概率的相继故障模型.对比了BA无标度网络和WS小世界网络上遭遇两种边袭击策略导致的全局相继故障现象,探讨了崩溃概率以及网络拓扑结构对边袭击策略的影响,并分析了网络有效预防相继故障发生的应对策略.数值模拟和理论解析的一致性也验证了结论的正确性.

关键词: 相继故障, 复杂网络, 崩溃概率, 袭击策略

Abstract: Since there exists a certain degree monitoring and control in real-life networks, not all overloaded edges will be removed from networks.We propose a mechanism of the breakdown probability of an overload edge, and construct a cascading model with the breakdown probabililty.We compare the universal cascading phenomena on BA scale-free and WS small-world networks subject to two different attacks on edges, investigate the effects of the breakdown probability and different network structures on edge attack strategies, and analyze coping strategies to prevent cascading failures.The consistency of numerical simulation and theoretical analysis also verifies the correctness of the conclusions.

Key words: cascading failure, complex network, breakdown probability, attack strategy
