MQTT (Message Queuing Telemetry Transport) is a widely used messaging protocol in Industrial IoT (IIoT) that enables real-time, low-bandwidth communication between devices. It is designed for constrained environments where network bandwidth and power consumption are critical concerns.
MQTT operates on a publish-subscribe model, allowing devices to send (publish) or receive (subscribe to) data through a broker. This makes it ideal for IIoT applications, such as remote monitoring, predictive maintenance, and real-time machine-to-machine communication.
By enabling efficient data transfer across industrial networks, MQTT plays a crucial role in modern smart factories, supporting real-time analytics, process automation, and machine-to-machine communication.
