SeNsIM-Web: A service based architecture for sensor networks 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 networks projects as it enables the cooperation and interoperability of different sensor platforms at an higher level of abstraction. In this paper we propose an innovative architecture for the interoperability of sensor networks; it is based on web services technologies, on the definition of a data model and on SeNsIM, an integration platform. The proposed architecture allows the development of complex applications by integrating heterogeneous data, which can be accessible through services according to standard data format and standard protocols.
