Edge Device Model for LoRaWAN Sensors duplexing

Our article deals with the Edge device model focusing on high-availability of Long-Range Wide Area (LoRaWAN) sensors for business-critical applications. We focus on creating a suitable Edge device model that ensures the high availability of sensor data for specific critical applications. The model was implemented in Node-RED software, based on the MQTT protocol, and subsequently validated to confirm the required duplication of LoRaWAN sensors values for application. In case of single failure, Edge model enables uninterrupted flow of sensors data for their processing by critical applications.
