Diseño e implementación de un protocolo de capa de aplicación para la transmisión de datos hidrometereológicos utilizando LoRaWAN: caso de estudio PROMAS

Abstract

The graduation project "Design and Implementation of an Application Layer Protocol for the Transmission of Hydrometeorological Data using LoRaWAN: PROMAS Case Study.Ït uses the long range and low power consumption LoRa technology as a WSN application. LoRa operates under the LoRaWAN protocol developed by the LoRa Alliance, and was designed for battery-based end devices. These devices connect to the central server through a Gateway in a star-star topology. Both LoRa and LoRaWAN offer solutions in the context of IoT and facilitate the implementation of monitoring systems in rural environments due to their easy configuration, low power consumption and long-range coverage. Since the main focus of this work is to monitor a remote and hard-to-reach area with low-speed Internet connections, the Gateway uses GSM/GPRS technology to transmit the data to the server. GSM is considered a second generation (2G) standard and GPRS, a 2.5G technology that enhances the GSM system.The main objective of this work is the implementation of the application layer protocol VMTPv2, designed specifically to work on LoRaWAN.This protocol runs between the sensor nodes and the server, and its objective is to adjust the payload based on the weather information carried, to minimize the size of the frame and reduce the total energy consumption of the system.
