Integrating an MQTT Proxy in a LoRa-Based Messaging System for Generic Sensor Data Collection

[EN] In this paper we use a frugal innovation approach to propose an efficient and generic solution to provide support to the deployment of IoT system in rural areas. Our proposal includes an MQTT (Message Queuing Telemetry Transport) proxy to integrate generic lowcost and low-power sensor devices in a messaging system based on LoRa (Long Range) technology. MQTT allows these data to be provided to external ¿data lakes¿ so that they can be used for tasks such as reporting, visualization, advanced analytic, and machine learning. LoRa technology provides long wireless links that can be used to connect villages and towns. Through a REST-based interface and using JSON as a lightweight data-interchange format, we show how our platform can be used to distribute generic sensor information from rural communities. Finally, we demonstrate through experimental evaluation that this solution provides stable data transfers over links of various kilometers with a minimal utilization of resources.This work was partially supported by the Ministerio de Ciencia, Innovacion y Universidades, Programa Estatal de Investigacion, Desarrollo e Innovacion Orientada a los Retos de la Sociedad, Proyectos I+D+I 2018, Spain, under Grant RTI2018-096384-B-I00.Nakamura, K.; Manzoni, P.; Zennaro, M.; Cano, J.; Tavares De Araujo Cesariny Calafate, CM.
