MQTT is an Instant Messaging protocol developed by IBM. MQTT is a connectivity protocol for both the machine and the internet of Things, with lightweight publishing and subscription messaging. The Mosquitto is an MQTT v3 implementation. The 1 Protocol's Open source message agent software provides lightweight, support for publish/ Subscribe message push mode, making device-to-device short message communication easy to use. In the first contact with the MQTT protocol, the following concepts are understood: "MQTT protocol Features"--the MQTT protocol provides better remote control than the restful architecture of the IoT system, with messaging push capabilities. The MQTT protocol role-The IoT system in the RESTful architecture, contains two role clients and server-side, while the MQTT protocol includes publishers, agents (servers), and Subscribers. The messages in the MQTT protocol message--MQTT can be understood as the content (payload) exchanged by the Publisher and Subscribers, which contain specific content that can be used by subscribers. The topic in the MQTT protocol topic--mqtt can be understood as a message collection of the same type or similar type listens for the port by default:1883: Mqtt, unencrypted 8883: mqtt, encryption  8884: MQTT, encryption, customer service requires authentication 8080: Mqtt through WebSockets, unencrypted
