ROSNet: A WMN based Framework using UAVs and Ground Nodes for Post-Disaster Management

Abstract

This paper presents a wireless mesh network-based solution utilizing stationary and mobile ground/UAV nodes for setting up a post-disaster communication infrastructure. The network is ad hoc and establishes connectivity over a large area without the use of a cellular network or the internet. We propose a complete end-to-end framework, where we deploy an android application on smartphones at the user-end, the wireless mesh network as the backbone of communication, and a graphical user interface (GUI) at a base station for facilitating situational awareness. The software stack is based on the Robot Operating System for broadcasting user information to the base station, and also for controlling the UAVs remotely. The GUI also incorporates a node recommendation strategy for selecting the optimal nodes. The framework is evaluated using UAVs and a semi-autonomous car, and the experimental results show that the proposed system could be indispensable in providing large-scale connectivity in post-disaster management.
