A Common Data Model for Sensor Network Integration

One of the main open issues in the development of applications for sensor network management is the definition of interoperability mechanisms among the several monitoring systems and heterogeneous data. Interesting researches related to integration techniques have taken place, they are primary based on the adoption of sharing data-mechanisms; furthermore in the last years, the Service-Oriented Architecture (SOA) approach has become predominant in many sensor network projects as it enables the cooperation and interoperability of different sensor platforms at an higher level of abstraction. In this paper we propose a novel architecture for the interoperability of sensor networks, which is based on Web services technologies and on the definition of a common data model enriched with semantic concepts and annotations. The proposed architecture allows the development of complex application by integration of heterogeneous data, accessible through services, according to standard data format and standard protocols.
