Abstract :The fourth industrial revolution is underway, driven by spectacular advances in IoT that are redefining the possibilities for equipment monitoring, automated diagnostics and remote control. In this changing landscape; our research has focused on accurately measuring the advantages of the MQTT protocol over its main competitors, HTTP and CoAP, in an environment that replicates real-world industrial conditions. To conducts this evaluation, we designed a comprehensive test bench combining several key technologies: DHT11 sensors for temperature monitoring and ACS712 sensors for electrical measurements, an ESP8266 processing unit managing data collection, a Mosquitto server installed on Raspberry Pi managing MQTT messages, all visualised using the Node-Red interface. After five days of intensive testing and analysis of 1,500 samples, the figures speak for themselves: MQTT clearly outperforms other protocols with an average response time of 150 milliseconds (with a margin of error of only 5ms), a transmission success rate of nearly 100%, and optimised energy consumption. This exceptional performance makes MQTT the ideal candidate for demanding industrial applications. However, a few practical challenges still need to be addressed for large-scale adoption: strengthening the security of exchanges via protocols such as TLS, facilitating connection with traditional industrial systems, and training technicians in these new technologies. This work paves the way for a more connected and intelligent industry, where the combination of MQTT with AI and edge computing could well revolutionise the way, we produce.
