FloatingBlue: uma arquitetura de RSSF de baixo consumo não infraestruturada baseada em redes tolerantes a atrasos e desconexões e Bluetooth Low Energy

Abstract

The implementation of WSN (Wireless Sensor Network) in large and remote areas poses challenges, such as the need for low power consumption and long-range communication reach. To overcome these challenges, this work proposes a new infrastructure-less network architecture called FloatingBlue, which combines mobile concentrator nodes (e.g., drones) equipped with delay-tolerant and disruption-tolerant communication technologies using the Bundle Protocol 7, and low-power termination nodes using Bluetooth Low Energy (BLE) protocol. The proposed architecture aims to increase network coverage and reduce energy consumption. The presented work describes the integration of these protocols into a computational module, the development of firmware for termination nodes, and their application in monitoring an agricultural area. The results obtained using FloatingBlue demonstrate success in collecting and transmitting environmental parameters in a vast area with a prolonged disconnection scenario. Additionally, satisfactory energy consumption results were identified for termination nodes: 42 μJ in transmission mode of bundles and 13 μJ in idle mode.
