Chessa S., Furfari F., Girolami M., Lenzi S. SAIL: a Sensor Abstraction and Integration Layer for Context Aware Architectures. Technical report, 2008.
Wireless Sensor Networks (WSN) are an important technological support for smart environments and ambient assisted applications. Up to now most applications are based on ad hoc solutions for WSN, and attempts to provide uniform and reusable application 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 approach, and they are interfaced with different access technologies. SAIL is currently encapsulated within the OSGi framework and has been tested with a WSN platform based on MICAz motes.
