MQTT (Message Queuing Telemetry Transport, ISO/IEC 20922) is a lightweight pub/sub messaging protocol widely used in SCADA and IIoT applications for sensor data collection and device control. MQTT brokers (Mosquitto, EMQX, HiveMQ) are commonly deployed in SCADA architectures for real-time telemetry streaming.
