有向复杂网络中的链接删除

Link deletion in directed complex networks

G. Kashyap, G. Ambika

摘要:

我们提出了一个系统和详细的研究下随机和有针对性的删除链接的有向网络的鲁棒性。我们使用一组随机和无标度类型的网络模型,这些模型具有聚类和重复性的特定特征。各种策略,如随机删除的链接,或删除基于介数中心性和程度的源和目标节点,被用来打破网络。研究了网络对链路持续丢失的鲁棒性,给出了网络连通分量大小和反向路径长度的表达式。聚类和2节点度相关性,对攻击的鲁棒性的影响,也进行了探讨。我们提供了具体的说明,我们的研究三个现实世界的网络构建蛋白质-蛋白质相互作用和运输数据。

英文摘要:

We present a systematic and detailed study of the robustness of directed networks under random and targeted removal of links. We work with a set of network models of random and scale free type, generated with specific features of clustering and assortativity. Various strategies like random deletion of links, or deletions based on betweenness centrality and degrees of source and target nodes, are used to breakdown the networks. The robustness of the networks to the sustained loss of links is studied in terms of the sizes of the connected components and the inverse path lengths. The effects of clustering and 2-node degree correlations, on the robustness to attack, are also explored. We provide specific illustrations of our study on three real-world networks constructed from protein-protein interactions and from transport data.
