BTMesh: framework para a criação de redes mesh sobre Bluetooth LE

Abstract

Nowadays the communication between mobile devices is done mostly over the Internet, which is dependent on carriers’ infrastructure. If these systems go down, by electronic fail or overflow, users would be unable to share information. As a solution to this problem, this work has the objective of presenting the research and development of a mobile framework to build mesh networks over Bluetooth Low Energy (BLE). It is being proposed the creation of a dynamic communication net between devices, even if they are not connected to the Internet. To do so has been conducted a research to understand BLE's behavior and limitations, network architectures, and reactive programming, to be able to design a protocol with good performance regarding bandwidth and power consumption. The results that could be seen in the experiments show the proposed frameworks' viability as a communication agent of mobile devices using BLE technology, even being in an early development stage.
