Abstract

Networks of cooperating low cost nodes are becoming more and more relevant components of modern information systems. This paper analyses how to apply a common web service paradigm to both small devices and Internet network nodes in order to promote systems interoperability and scalability. REST style and SOAP protocol are matched up with the typical resources of small devices and are applied to the development of a two layer service oriented architecture that merges different classes of nodes. Small devices perform basic tasks, such as environmental sensing and conditioning, and interface with nodes that offer more complex services on the base of the collected results. A prototype has been developed to validate the proposed architecture. It is based on very cheap hardware devices and demonstrates that a REST-based web service approach is possible.
