Abstract
After a disaster happens, effective communication and information sharing between emergency response team members play a crucial role in a successful disaster response phase. With dedicated roles and missions are assigned to responders, role-based communication is a pivotal feature that an emergency communication network needs to support. Previous works have shown that Named Data Networking (NDN) has many advantages over traditional IP-based networks in providing this feature. However, these studies are only simulation-based. To apply NDN in disaster scenarios, real implementation of a deployment architecture over existing infrastructure during the disaster should be considered. Not only should it ensure efficient emergency communication, but the architecture should deal with other disaster-related challenges such as responder mobility, intermittent network, and replacement possibility due to disaster damage. In this paper, we designed and implemented an NDN-based disaster response support system over Edge Computing infrastructure with KubeEdge as the chosen edge platform to solve the above issues. Our proof-of-concept system performance shows that the architecture achieved efficient role-based communication support, fast mobility handover duration, quick network convergence time in case of node replacement, and loss-free information exchange between responders and the management center on the cloud.

Summary
Disaster Response is the second phase in the four-phase process of Disaster Management (Preparedness, Response, Rehabilitation and Reconstruction, Mitigation)—a process that government and authorities follow to reduce potential damage from hazards, assure prompt and appropriate assistance to victims during a disaster, and recover after that according to WHO training package document [1]. Disaster Response happens immediately aftermath of a disaster and aims to minimize the damage by conducting assistance services (searching and rescuing), distributing supplies, and medical care. In this phase, emergency responders are normally divided into teams with different missions. Reliable and timely information exchange between these responders and their commanders is the key to make an effective disaster response phase. Infrastructure is usually damaged and broken after a disaster happens
