Abstract: In this paper, the scale-free network discovery is reviewed and the scale-free characteristic of complex networks is described, based on the strategies which are proposed against vulnerability of hubs in scale-free networks. The strategies show how hierarchy is formed by controlling hubs and how nodes generate super-cube consisting of virtual nodes in detail. The hierarchy of nodes has better flexibility and fault tolerance; besides, the super-cube structure has fault reconfiguration compared with hubs. Both have higher robustness and steadiness shown by simulation.
Key words: super-cube structure, scale-free networks, hubs, hierarchy structure
摘要: 本文回顾了无尺度网络的发现历程,论述了复杂网络的无尺度特性,并在此基础上提出了集散节点的抗脆弱性策略。提出了对集散节点加以控制后形成的层次和由虚拟节点组成的超立方体。与原集散节点相比较,层次结构具有较高的灵活性和容错性,超立方体结构具有高度自治性与故障重构性。仿真实验表明两者都具有较强的鲁棒性、稳键性。
关键词: 超立方体结构, 无尺度网络, 集散节点, 层次结构
