Design and implementation of a communication protocol for mobile device controlled smart home management system

Recently, with the increase in mobile and internet accessibility, it has become widespread that smart home systems can be managed remotely and monitored by mobile devices. In this study, a communication protocol between a mobil devices-embedded PC based control unit-sensors/actuators is designed and implemented. A handshaking mechanism between a mobile device and control unit, and packet structure for messaging between control unit and sensors/actuators are explained. With this system, the smart home system can be controlled over a wireless LAN by authorized users using an Android based mobile device on which the implemented GUI software is running.
