Serviço de mensageria utilizando redes tolerantes a atraso

Abstract

The problem with current messaging applications, is that it is dependant on Internet connection. This, in turn, is dependant on infrastructure, which can be, for example, compromised from interference of natural disasters, censored or surveilled by providers (ISP), be unable to reach remote locations, and comes with financial obligations, a limiting factor for low-income people. The proposal of this project is to develop a messaging application for Android devices, where the communication is done in an encrypted, decentralized, peer-to-peer and Internet-independent manner. This is done by using the Wi-Fi Direct technology, where every smartphone acts like a node in a DTN (delay tolerant network), using other physically close enough nodes for the hops, creating a communication infrastructure only from the smartphones themselves.
