Message Queuing Telemetry Transport

MQTT is a lightweight, publish-subscribe messaging protocol designed for communication between devices in IoT and embedded systems. It operates over TCP/IP networks and uses a broker-based architecture where devices can publish messages to topics and subscribe to receive messages from specific topics. The protocol is optimized for low-bandwidth, high-latency, or unreliable networks, making it ideal for connecting sensors, actuators, and other hardware devices to cloud services or local networks with minimal overhead.
