MQTT (Message Queuing Telemetry Transport)

MQTT, or Message Queuing Telemetry Transport, is a lightweight messaging protocol used for communicating between devices over the internet. It enables efficient data transmission between hundreds or thousands of connected devices, often in the context of the Internet of Things (IoT). MQTT works on a publish-subscribe model, where devices can send (publish) messages or receive (subscribe) to messages without needing to know each other's identities. This approach minimizes network traffic and ensures reliable delivery even in low-bandwidth or unreliable scenarios, making it ideal for applications like smart homes, industrial automation, and remote monitoring.
