A Universal Implementation Model for the Smart Home

Since the emergence of the smart-home concept, many devices, interfaces and controllers have become available. However, there is a problem: each component usually performs a single function and there is no synchronization with other components. In order to exploit the great potential of the new technologies that these devices embody, as a base for synchronizing devices, interfaces and intelligent control systems, a universal model is required. The current paper offers a universal, comprehensive model for a smart home. Drawing upon existing protocols and technologies, it illustrates how to integrate different devices, software, and user interfaces to create a smart home. The model emphasizes four principles: A universal model can substantially lead to higher quality and usability of both devices and user interface; Production costs may be significantly reduced if manufacturers adopt a universal standard; The model synchronizes different groups of devices. This makes it possible to program complex scenarios leading to improved and enhanced smart-home utilization; Based on current available communication standards and infrastructure, the model can easily be installed in any house. Proposed smart-home architecture comprises in addition to appliances and communication interfaces a central management unit and a built-in database for smart equipment integration, for creating and implementing preprogrammed complex scenarios. The central management unit application and database store an up-to-date list of all connected devices. Any new integrated device is synchronized upon connection and removed when not in use. This is done automatically by sending any shared data (list of properties, commands, optional streaming, etc.) into the database upon initial connection.
