Performance of LORA Gateway MQTT Protocol Communication on Motor Cycle IoT-Based: A QoS Analysis

In IoT-based systems that utilize platforms for data exchange, reliable and efficient communication methods are essential to enable users to search for and monitor system data. Similarly, in IoT -based motorcycle security protection systems, dependable communication methods are crucial. LoRa and the MQTT protocol serve as solutions for data communication in the IoT system implemented in this research. To evaluate the reliability of the system's communication, tests were conducted under LOS (Line of Sight) and NLOS (Non-Line of Sight) conditions, with optimal transmission ranges of 500 meters for LOS and 300–325 meters for NLOS. The analysis was based on test parameters, including a delay of 122.25 ms, a throughput of 66.75 bps, and a packet loss rate of 1.5%. The LoRa testing across different ranges yielded RSSI values of -115 to -71 dBm under LOS conditions and -122 to -52 dBm under NLOS conditions. These test parameter results for LoRa and MQTT communication fall into the excellent category with a high SF 12 value. Additionally, the Telegram Bot platform was successfully integrated into the motorcycle security protection system, enabling remote control and monitoring. Notifications and data from sensor nodes are received by users through the Telegram Bot, demonstrating the system's effectiveness.
