Abstract

This paper presents a research project focused on developing a bidirectional communication mechanism for the intercommunication of the Wireless Sensor Network (WSN) IoT. This communication occurs between the network nodes (without Internet access) and the central node (connected to the Internet), a service API, a cloud-based database, and a mobile app with a graphical interface for data consultation. The nodes are equipped with digital sensors for measuring temperature, humidity, water level, and GPS coordinates. The primary contribution of this work is directed towards enhancing the communication mechanism (protocol) among IoT devices within a wireless network (WSN). It aims to provide security and reliability benefits in the reading, transmission, and sending of data across the network. The communication mechanism employs data encryption in the standard JavaScript Object Notation (JSON) communication format. The sections included in this research cover: The assembly of the LoRa+Antenna device, sending data between devices with standard data encryption and data packets in JSON format, and consumption of APIs in the cloud for storage and querying of information from the sensors.
