This paper describes the Sensor Alert Web Service (SAWS) for the Institute of Electrical and Electronics Engineers (IEEE) 1451-based sensor networks developed at the National Institute of Standards and Technology (NIST). The SAWS consists of the Sensor Alert Notification Producer Service (SANPS) and Sensor Alert Notification Consumer Service (SANCS). The SANPS and SANCS are described in the Web Service Description Language (WSDL) based on Web Services Notification (WS-Notification). A SAWS prototype system consisting of a SAWS consumer, a SAWS provider, and an IEEE 1451.5-802.11 wireless sensor node is presented in the paper. When a sensor reading exceeds the preset sensor thresholds, the SAWS provider will automatically send to the SAWS consumer a sensor alert message described in the Common Alert Protocol (CAP). A case study of sensor alerts is presented to validate the SAWS system.
