MQTT

MQTT (Message Queuing Telemetry Transport) is a lightweight, publish-subscribe messaging protocol.

MQTT is ideal for the Internet of Things (IoT) and machine-to-machine (M2M) communication, designed for low bandwidth, high latency, or resource-constrained networks. It uses a central broker to manage messages, decoupling publishers (devices sending data) from subscribers (devices receiving data) through topics, making communication efficient and scalable.
