双向相关网络的鲁棒性分析与设计

Robustness of Bidirectional Interdependent Networks: Analysis and Design

Marzieh Parandehgheibi, Eytan Modiano

摘要:

我们研究的鲁棒性的相互依赖的网络,两个网络被称为是相互依赖的,如果一个网络的操作依赖于另一个的操作,反之亦然。在本文中,我们提出了一个模型,用于分析具有已知拓扑结构的双向依赖网络。我们将度量MR(D)定义为应该从一个网络中移除的节点的最小数量,以导致另一个网络中的D个节点由于级联故障而失效。我们证明了评估这个度量不仅是NP-完全的,而且是不可逼近的。接下来,我们提出了用于评估此度量的算法,并使用仿真结果比较它们的性能。最后,我们介绍了两个密切相关的定义,相互依赖网络的鲁棒设计,提出了显式设计的算法,并证明了鲁棒相互依赖网络和扩展图之间的关系。

英文摘要:

We study the robustness of interdependent networks where two networks are said to be interdependent if the operation of one network depends on the operation of the other one, and vice versa. In this paper, we propose a model for analyzing bidirectional interdependent networks with known topology. We define the metric MR(D) to be the minimum number of nodes that should be removed from one network to cause the failure of D nodes in the other network due to cascading failures. We prove that evaluating this metric is not only NP-complete, but also inapproximable. Next, we propose heuristics for evaluating this metric and compare their performances using simulation results. Finally, we introduce two closely related definitions for robust design of interdependent networks; propose algorithms for explicit design, and demonstrate the relation between robust interdependent networks and expander graphs.
