Message Queuing Telemetry Transprt

The MQTT protocol is a straightforward method for exchanging messages between devices and components, such as smart sensors, that are limited to restricted functions. It is based on the publish-subscribe method and was developed specifically for unreliable, low-bandwidth, high-latency networks such as those found in low-power wide area networks (LPWANs). Due to its simplicity and robustness, MQTT is often used in these networks.
