Middleware-Based Distributed Data Acquisition and Control in Smart Home Networks
For each of the networking techniques widely adopted in the field of home appliance control has its strength and weakness, it is more desirable to use multiple network technologies at the same time. Multi-platform smart home system would be an objective existence. In general point to point method, with the increasing of underlying hardware units and upper applications, the complexity of the central control unit will increase linearly. By using a universal home control middleware adapter, we decouple the application layer from the hardware layer, and make it possible to enable distributed data acquisition and control in a multi-platform smart home system. Many validated methods efficient to implement distributed data acquisition and control are discussed under this architecture, like using a timer or special thread with the unified API of the middleware adapter, redefinition callback or delegation functions for one type of the application interface, or using middleware integrated database to directly save the collected data. For each of these discussed methods, higher quality and usability both of devices and user interfaces, higher performance, lower production costs and loose-coupled hardware networks of different technologies are concerned.
