Massively deployed wireless sensor and actuator networks (WSAN), co-existing with RFID technology, can bring clear benefits to large-scale enterprise systems, by delegating parts of the business functionality closer to the point of action. However, a major impediment in the integration process is represented by the variety of customized WSAN platforms and proprietary technologies. In this paper, we present a three-layer service-oriented architecture that accommodates different sensor platforms and exposes their functionality in a uniform way to the business application. Our work is motivated by real business cases from the oilgas industry. In our implementation, we use three sensor platforms (Particle, Node and Sindrion) integrated through the UPnP standard and incorporated into SAP enterprise software. The practical tests and application trials confirm the feasibility of our solution, but also reveal a number of challenges to be taken into account when deploying WSAN on industrial sites.
