Towards the Web of Things: Using DPWS to bridge isolated OSGi platforms

Bringing heterogeneous devices like industrial machines, home appliances, and wireless sensors into the Web assumes the usage of well-defined standards and protocols. Our approach combines the Web Service standard for devices DPWS with the embedded system and component management standard OSGi. It implements the specifications of OSGi Remote Services, as well as OASIS Discovery, Eventing, SOAP-over-UDP, and DPWS. Furthermore, runtime WSDL generation and interpretation is supported, as well as the presentation URL feature which automatically provides a web browser user interface for interactive device access. Thus, our approach is an appropriate and comprehensive basis for the seamless, flexible, and standard-compliant integration of things into the Web.
