By the virtue of blooming automation industry and wireless connectivity, all the devices within the home can be connected. This improves the comfort, energy efficiency, indoor security, cost savings of the home. Small and constrained embedded devices are used to remotely monitor the conditions within home and control the home appliances. In such case, power consumption and network bandwidth become a major concern. A low power device that transmits messages through a less verbose protocol is needed. Owing to the ubiquitous availability of WiFi, all the appliances within home can be connected through a common gateway. An overview of a light weight Message Queuing Telemetry Transport (MQTT) protocol is presented here. In the prototype, we attempt to implement MQTT on Raspberry PI, a WiFi based development board. Sensors and actuators are connected to Raspberry PI and a Mosquitto based MQTT broker is established for remote monitoring and control. The use of MQTT hence achieves the desired result with a lower overhead and at about a 93% faster speed. The intruder detection is an added useful functionality to the system.
