A multi-layer architecture for distributed data acquisition

This paper describes an architecture for distributed control of a sensors network through Internet. The architecture is based on a multiple layer structure that allows scalability when a large number of sensors is planned. Accounting and access policies are also addressed. Since standard web interfaces are adopted, the architecture allows an easy integration with already available products to be obtained. A practical case-study is also presented where sites in different cities cooperate for data retrieval from different sensors.
