Mosquitto: server and client implementation of the MQTT protocol

Mosquitto provides standards compliant server and client implementations of the MQTT messaging protocol.MQTT uses a publish/subscribe model, has low network overhead and can be implemented on low power devices such microcontrollers that might be used in remote Internet of Things sensors.As such, Mosquitto is intended for use in all situations where there is a need for lightweight messaging, particularly on constrained devices with limited resources.
