The design and implementation of home appliance control based on information from sensors is presented. In a ubiquitous networking society, there are a lot of devices connected to a network. However, many kinds of networks coexist, and they use different communication protocols. Therefore, a technology to integrate different networks is necessary to provide flexible services, which can control various devices connected to different networks where different protocols are used. At the same time, the technology of sensor networks is important in such a society. Sensors also use different protocols. Therefore, using sensing data from different kinds of sensor networks is difficult. To collect and process information from various kinds of sensors, we designed and implemented a Sensor Gateway. To control home appliances, protocols defined by the Peer-to-Peer Universal Computing Consortium are used in our system.
