Power Failure Emulator for Communication Network in Disaster Situation Kei Hiroi, Akihito Kohiga, Sho Fukaya, Yoichi Shinoda

Abstract

Communication networks often experience failures during natural disasters such as floods, making it difficult for affected individuals to access critical information. This research proposes a power failure emulator that reproduces the interdependencies between communication failures and power supply during flood events. The emulator models the behavior of ground- based substations and determines the power supply status in flood-affected areas. It is designed to work in coordination with multiple interdependent simulators and systems, including a flood analysis simulator, an evacuation simulator, a communication failure emulator, and an evacuation route information system, using a federation strategy. The power failure emulator exchanges information with other components via a federation bus, communicating the state of power supply to the communication failure emulator, thus reproducing the impact on communication networks. The objective is to generate more realistic scenarios that consider the interdependencies between power supply and communication networks during natural disasters, enabling the analysis of the impact of communication failures on information access for affected individuals and facilitating the development of more effective disaster response strategies.
