Insight
Mosquitto is an open source (BSD licensed) message broker that implements the MQ Telemetry Transport protocol version 3.1. MQTT provides a lightweight method of carrying out messaging using a publish/subscribe model. This makes it suitable for 'machine to machine' messaging such as with low power sensors or mobile devices such as phones, embedded computers or micro-controllers like the Arduino.
