A Service-Based Architecture for the Interoperability of Heterogeneous Sensor data: A Case Study on Early Warning

Abstract

AbstractOne 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 a higher abstraction level.In this chapter we propose an architecture for the interoperability of sensor networks; it 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 integration of heterogeneous data and the implementation of Web Services to let data (raw or aggregated) be available to authorized end-users. Finally, we will present an early warning service with the definition of a common data model for a specific class of sensors.KeywordsSensor NetworkSensor DataEarly Warning SystemSensor ObservationCommon Data ModelThese keywords were added by machine and not by the authors.
