摘要
利用仿真分析的方法将耦合映像格子(Coupled Map Lattice,CML)的相继故障模型作用于节点数固定的Km,n网络拓扑结构中,旨在分析在蓄意攻击和随机攻击两种方式下,Km,n网络拓扑结构的稳定性和影响Km,n网络拓扑结构相继故障规模的参数。仿真结果表明:蓄意攻击更容易引起Km,n网络拓扑结构的全局故障;在两种攻击方式下,网络都表现出了"鲁棒但又脆弱"的基本特征;Km,n网络拓扑结构的特征值是影响网络相继故障规模的又一新的参数。
We have CML cascading failure model acted on the Km,n network topology with fixed node number through simulation methods to analyze the network stability and the parameters that affect the size of Km,n network topology cascading failure in the deliberately attacking and randomly attacking.Simulation results show that deliberate attacks are more likely to cause global fault of Km,n network topology;on the other hand,the network all exhibits a basic feature of ＂robust but fragile＂ in the two kinds of attack;at the same time,the eigenvalue of Km,n network topology is a new parameter that affects the scale of cascading failure of the network.
