Estudo e proposta de ferramenta para comunicação em ambientes de desastres

Abstract

The disaster management is a systematic process that aims to reduce the negative impacts of disasters. It describes how rescue operations should be conducted, organized, and the each professional role on the operation. Whereas over a traditional media disaster can be found damaged, this paper proposes the development of an application for mobile devices that can aid communication of rescue teams during a response operation to a disaster incident. This application should allow a communication between devices over a infrastructure less network that connects the devices directly to each other. For that,Wireless network technologies available in popular smartphones were studied. The Wi-Fi Direct, among the technologies studied, was the most efficient to create peer to peer networks, allowing data exchange between devices up to 80 meters away from each other and a transfer up to 11Mbps. Using this technology was developed an aplication which is avaliable to send text messages and standarized messages, based on the international Q code to a network consisting several devices connected directly each others.
