Chessa S., Furfari F., Girolami M., Lenzi S. SAIL: a sensor abstraction and integration layer for context awareness. In: 34th EUROMICRO Conference on Software Engineering and Advances Applications - Special Session on Software Architecture for Pervasive Systems (SAPS) (Parma, Italy, 03-05 September 2008). Proceedings, pp. 347 - 381. IEEE/CS, 2008.
Wireless Sensor Networks (WSN) are an important technological support for ambient assisted applications. Up to now most WSN applications are based on ad hoc solutions, and attempts to provide reusable applications are still in their youth. Under this trend of research we propose a layered architecture called SAIL (Sensor Abstraction and Integration Layers) to be used in context aware architectures, and aimed at integrating WSN as context information sources. In the proposed approach, the applications running on WSN can be exposed using either a node centric or a data centric paradigm, and they are interfaced with different access technologies. SAIL is currently encapsulated within the OSGi framework and has been tested on MICAz motes.
