Extending the Devices Profile for Web Services Standard Using a REST Proxy
Son N. Han, Soochang Park, Gyu Myoung Lee, Noël Crespi · IEEE Internet Computing · 2014
The Devices Profile for Web Services (DPWS) standard enables the use of Web services for certain Internet of Things (IoT) applications. DPWS is appropriate for implementing services on resource-constrained devices. However, little investigation has gone into how such services perform in IoT scenarios as regards features such as dynamic discovery and publish-subscribe eventing. Moreover, DPWS introduces considerable overhead due to its use of SOAP envelopes in exchange messages. To tackle these problems, the authors extend the DPWS standard using a REST proxy, creating a RESTful Web API that paves the way for developers to invest more in this technology.
