Abstract: A disaster may not necessarily demolish the telecommunicationsinfrastructure, but instead it might affect the national grid and causeblackouts, consequently disrupting the network operation unless there is analternative power source(s). In this paper, power outages are considered, andthe telecommunication network performance is evaluated during a blackout. Twoapproaches are presented to minimize the impact of power outage and maximizethe survival time of the blackout node. A mixed integer linear programming(MILP) model is developed to evaluate the network performance under a singlenode blackout scenario. The model is used to evaluate the network under the twoproposed scenarios. The results show that the proposed approach succeeds inextending the network life time while minimizing the required amount of backupenergy.
