Smart home automation with MQTT

This paper aims to investigate the main advantages brought by Message Queuing Telemetry Transport (MQTT) protocol which is used by Internet of Things (IoT) devices. In addition to the advantages brought by the MQTT protocol in the smart grid environment we will also analyze the challenges and limitations that are introduced by it and were it should be adopted in the current smart grid. As a study case for this paper the practical implementation of MQTT in a smart home automation system will be presented.
