MQTT Protocol

The MQ Telemetry Transport (MQTT) is a Client Server publish/subscribe transport messaging protocol that runs on TCP/IP. MQTT is simple and lightweight, designed to have a small footprint on clients with limited capacity. MQTT is meant to be used in low bandwidth, high latency networks, designed to minimize the use of the network bandwidth to ensure higher quality of service and reliability when transporting the message. MQTT is mostly used for Machine- to-Machine (M2M) and Internet of Things (IOT).
