# Named Data Networking Based Disaster Response Support System over Edge Computing Infrastructure +
###### 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. n

**1. Introduction**  
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. However, several challenges make it difficult to communicate efficiently in a disaster scenario. First, infrastructure is usually damaged and broken after a disaster happens. With the messaging server is down, most normal centralized message delivery applications cannot work. Second, communication using the current IP-based network show limitations. Considering responders' dynamic roles and high mobility when participating in the disaster response phase, it is difficult to know each individual IP address to contact. This causes a significant delay in emergency information delivery during the disaster. As a result,inappropriate resource allocation, late assistance when rescuing people happen and these issues can lead to unwanted and serious consequences. Because of these challenges, it is necessary to find a network solution that has mobility built-in support and enable location-independent, role-based group communication between responders. In recent years, several studies [2; 3; 4] have shown that Information-Centric Networking (including NDN--one of its architectures) can improve IP-based network weaknesses in providing these mentioned features in disaster. Specifically, NDN uses the content name as the main entity inside the network to route the packet instead of IP address-content location in IP-based network.
