A Sensor Web Middleware With Stateful Services for Heterogeneous Sensor Networks
Source: University of Melbourne
As sensor networks become more pervasive there emerges a need for interfacing applications to perform common operations and transformations on sensor data. Web Services provide an interoperable and platform independent solution to these needs. A key challenge of using Web Services in this context is how to support ongoing sensor queries that persist over an extended period of time. This paper introduces Web Service Resource Framework (WSRF) mechanisms into the core services implementation of the NICTA Open Sensor Web Architecture (NOSA).
