Smart Transducer Web Services Based on the IEEE 1451.0 Standard

This paper describes the proposed smart transducer Web services (STWS) developed at the National Institute of Standards and Technology (NIST) based on the IEEE 1451.0 standard. The STWS are described in WSDL (Web service description language). A prototype system has been established to test the STWS. This prototype system consists of a service consumer, service provider (wireless network node), and wireless sensor node. The service consumer and provider can communicate with each other through SOAP (simple object access protocol) messages. The STWS were tested successfully through a case study of reading an IEEE 1451 TEDS (transducer electronic data sheet). The proposed STWS provide a standard way for IEEE 1451 applications to achieve interoperability with other sensor applications in WSDL. Hence it provides a foundation for STWS standardization.
