OASIS standard messaging protocol for the Internet of Things. Lightweight publish/subscribe transport for remote, constrained devices. Current version is MQTT 5.0 (predecessors 3.1, 3.1.1). Three QoS levels (0 at most once, 1 at least once, 2 exactly once), retained messages, last-will, persistent sessions, MQTT over WebSockets, TLS, and OAuth / JWT authentication. MQTT-SN targets very constrained networks.
