“…In this context, self-healing methods have been proposed for the quick recovery of distribution networks (17) and the effects of power-communications coupling have been studied. Overall, the new trends have clearly shown the need for introducing a certain level of realism in the statistical modeling of power grids by the inclusion of flow dynamics and conservation laws (18).…”

“…The impact of failures in the power grid on the communication network was explored in [16], and the impact of power failures on layered optical communication networks was studied in [17]. In [18], [19], the interdependency model for power grid and communication network was modified by considering the power flow equations and cascading failures inside the power grid. In particular, we showed in [18] that under some conditions, the connectivity model proposed in this paper can be used to describe the cascading failures between interdependent power grid and communication networks.…”

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.
