Abstract

The article discusses the Protocol MQTT (Message Queue Telemetry Transport) Internet of things, its features, applications, characteristic procedures. The different equal qualities of service in MQTT are explained. The analysis of information elements and messages. The justification for choosing the level of service that meets the requirements of network reliability and application logic is made. It is proved that objectively the routing paradigm shifts from routing at the transport layer to routing at the application when serviced by IOT. It is shown that the topicality of the topic is due to the rapid development of the "publisher-subscriber" architecture, for which the protocol is most characteristic. The relevance of the topic is due to the streaming development of the publisher-subscriber architecture, for which this protocol is the most characteristic.

Keywords: Internet of Things, IoT, MQTT, Subscriber Publisher, Broker, QoS, Quality of Service.
