SStreaMWare

Smart sensors are already being used in various application domains such as medical, environmental, urban, domestic and industrial. These applications mostly need data from sensors of different types (temperature, pressure, location, camera, etc.) that may be managed by different software, e.g., proprietary software from manufacturers. Heterogeneous distributed sensor data should then be aggregated in order to obtain more accurate and complete information on real world events. This paper proposes SStreaMWare, a service-oriented middleware for heterogeneous sensor data management. SStreaMWare's simple data schema allows data representation of various types of sensors in a common generic way. Declarative queries can then be formulated according to this schema. Thanks to the service-oriented approach of SStreaMWare, heterogeneity of sensor software is hidden by generic query services, which can be discovered and used dynamically.
