Blackout Resilient Optical Core Network

TL;DR

This paper evaluates the resilience of optical core networks during power outages, proposing models to extend network lifetime and reduce backup energy needs in blackout scenarios.

Contribution

It introduces a MILP model for assessing network performance during blackouts and proposes two strategies to enhance network survivability and backup efficiency.

Findings

The proposed approach extends network lifetime during blackouts.

It minimizes the required backup energy for network operation.

The model effectively evaluates network resilience under blackout conditions.

Abstract

A disaster may not necessarily demolish the telecommunications infrastructure, but instead it might affect the national grid and cause blackouts, consequently disrupting the network operation unless there is an alternative power source(s). In this paper, power outages are considered, and the telecommunication network performance is evaluated during a blackout. Two approaches are presented to minimize the impact of power outage and maximize the survival time of the blackout node. A mixed integer linear programming (MILP) model is developed to evaluate the network performance under a single node blackout scenario. The model is used to evaluate the network under the two proposed scenarios. The results show that the proposed approach succeeds in extending the network life time while minimizing the required amount of backup energy.
