Automatic Domotic Device Interoperation

Current domotic systems manufacturers develop their systems nearly in isolation, responding to different marketing policies and to different technological choices. While there are many available approaches to enable interoperation with domotic systems as a whole, few solutions tackle interoperation between single domotic devices belonging to different technology networks. This paper introduces an automatic device-to-device interoperation solution exploiting ontology- based semantic device modeling. By explicitly modeling interoperation through ontology concepts and relations, the devised solution allows to automatically generate devicelevel interoperation rules. These rules, executed by a suitable rule-execution layer integrated in an intelligent domotic gateway (DOG), allow interconnecting arbitrary devices in a general and scalable manner. A case study is shown, where the automatic-generation of interoperation rules is applied to two real-world demo cases, with either KNX or BTicino devices.
