Desarrollo de un prototipo de red MESH basada en dispositivos RASPBERRY PI para la comunicación en situaciones de desastres.

Abstract

This undergraduate project involves the deployment of a simple and inexpensive infrastructure mesh network to which survivors' smartphones will be connected as if it were a common WiFi network. The mesh network uses Raspberry Pi microcomputers, and the connectivity between them is established through WiPi-type WiFi modules. With this mesh network, and depending on the number of Raspberry Pi devices that comprise it, the coverage of the area affected by a disaster could be significantly expanded, compared to the network generated only by smartphones. Inclusive, the members of the rescue teams could connect to it to locate and establish contact with the survivors in a more agile way. The network can be deployed on the Earth's surface (provided that post-disaster conditions allow it), or drones can be charged to charge Raspberry Pi devices when it is impossible to install it directly on the ground. This graduate work proposes the development of a prototype of the described mesh network, made up of 3 Raspberry Pi 3B + devices. Although similar mesh networks have already been implemented, also for humanitarian purposes, the knowledge and experience acquired in this process will be of great value to the research team and to the formulation of a proposal for the second phase of the research project.
