For future application scenarios of resource constrained and low cost smart cooperating objects, miscellaneous technologies for wireless connectivity are existing or upcoming in the near future. But further cross domain middleware and dedicated communication protocols to provide syntactic and semantic interoperability and not only technical interoperability are still missing. Thus, this paper investigates on two major candidates for IP based low power communication, based on known and matured technologies and protocols. Therefore, analyses and pitfalls of RESTful architectures based on HTTP and the Devices Profile for Web Services are presented. Furthermore, the paper discusses differences of DPWS and RESTful design and furthermore proposes an approach for a generic mapping of emerging Bluetooth Low Energy technology with RESTful device architectures for seamless and transparent connectivity.
