Técnicas de Geolocalização em Redes LoRaWAN como Abordagem de Tolerância a Falhas para Dispositivos IoT Baseados em GPS
Abstract
The wide adaptation of the concept of Internet of Things (IoT) and smart cities involves increasing the reliability and availability of applications in the face of failures. Long-range, low-power networks are used in such applications to provide connectivity. In this context, object tracking is an important feature. Usually GPS is used for that purpose. However, GPS failure may compromise the application. This work implements a hybrid geolocation strategy in LoRaWAN networks. The implementation is compared to a commercial tool where an environment with three gateways LoRaWAN was set up to perform an evaluation. Results show errors of about 151 and 19 meters in the worst and best case, respectively.
