Web services for IEEE 14511 sensor network controllers

Abstract

The following thesis entails the development and a feasibility study for the integration of a Service Oriented Architecture platform applied to the IEEE 1451 Sensor interface standard. The research work leverages a service oriented software-development approach via the XML Web Services Integration Framework (XWIF) process for exposing a sensor controller's application services to remote clients via web service based interfaces. Further, the J2EE framework hosts a web services based middleware. The J2EE middleware provides WSDL service interfaces for exposing operations required for sensor interaction, and a web-services communication mechanism via the SOAP XML based messaging protocol. The thesis extends the IEEE 1451.1 instrumentation standard's based platform, by introducing a software development model for web-services based sensor network applications. The prototype architecture of a web enabled 1451.1 NCAP controller connectable via the web-services middleware is investigated. Further, the research contribution presents the feasibility for introducing a service-oriented approach to distributed sensor monitoring via the developed web-services based NCAP platform connected to a real-time smart multi-sensor. Moreover, this thesis will provide the academic and instrumentation scientific community a performance study for integrating emerging web-service technologies within the instrumentation domain.
