摘要：This paper proposes a new framework for semantically interpreting and processing information of various types of sensors in heterogeneous sensor network environments. The ideal ubiquitous computing environment allows any devices interpret and use information from any sensors on mixed sensor networks. However, existing systems consider only the restricted environment where semantics of sensor information used by devices are predefined. To resolve this issue, various approaches have been studied, but there still remain several problems to realize the ubiquitous computing environment. This paper proposes a novel framework for achieving the seamless semantic interoperability. The proposed framework registers and manages information of heterogeneous sensors as well as their data. The concept of proposed framework is inherited from ISO/IEC 11179 - Metadata Registry. This paper also shows a prototype system and accomplishes a comparative evaluation against the previous approaches. The proposed framework is capable of the instant sensor data processing and enables sensor devices to use precise context information. It also supports semantic information extensibility by providing a dynamic semantic management facility.
