Mqtt is a one of the leading protocol in Internet of things. The Mqtt stands for Message Queuing telemetry transport. This protocol is based on PUB-SUB model.  The Broker, Publisher and a subscriber are required for the communication. This protocol operates over Wi-Fi..

Thus publisher does not which client is receiving this message and the subscriber client does not know which publisher has transmitted the message. Mqtt is a lightweight protocol hence can be easily used by Constrained application based device where low memory is available like microcontrollers, Arduino, Raspberry pi etc,
