MQTT

MQTT, or Message Queuing Telemetry Transport, is a lightweight messaging protocol designed for efficient communication between devices over the internet. It operates on a "publish-subscribe" model, where devices can send messages (publish) or receive messages (subscribe) on specific topics. This makes it ideal for applications like smart home devices, where many sensors and actuators communicate with minimal data usage. MQTT is particularly useful in environments with limited bandwidth or unreliable connections, as it ensures messages are delivered reliably and efficiently, making it popular in the Internet of Things (IoT) ecosystem.
