As we already posted, the CEBIT in Hannover and the Embedded World on Nürnberg are getting closer. So we posted a preview on the CEBIT demonstrator a few days ago, showing WS4D-uDPWS in action (see the SpO2 finger clip sensor).
Now would like to give a preview on the Embedded World demonstrator here. The video shows our Smart-Window, opening and closing depending on the humidity. The involved technologies are 6LoWPAN, IPv6, CoAP, DPWS, Digitalstrom and several of our existing WS4D tools. Feel free to comment…
The WS4D group developed an alternative security profile for DPWS, the WS4D Security Profile. Its purpose is to enable mobile devices – such as smart phones or netbooks – to securely communicate over DPWS. An implementation in alpha state as well as documentation on how to secure your applications is available in the WS4D-gSOAP trunk. The highlights are
direct authentication between devices (no authentication server, no certificate authorities)
highly flexible authorization subsystem
in nearest future: fine-grained configuration of security constraints
Of course, we provide an additional version of the well-known air conditioner example – this time using the security profile’s implementation. Check it out!
The TeKoMed project evaluates the deployment of Service-oriented Architectures also in medical applications like operating-rooms. DPWS is the core technology, of course. From 23.-24.11. the 2nd TeKoMed workshop was held in Luebeck and the WS4D folk was represented strong there. Main discussions were around security of patients data, which is a significant challenge and a major requirement in medical applications. But also semantic concerns and discussions about moral and ethical issues like the ‘best DPWS framework’ have been raised. So the variety of topics lead to fruitful discussions.
There will be two more workshops of the TeKoMed project so stay tuned and feel free to join!
There is a new research project investigating into security issues of the WS4D technology. Therefore the project will realize a toolkit called WS4Dsec that enables a combined development and verification process for WS4D-enabled devices ensembles.
We are happy to announce the release of the newest DPWS stack at WS4D. uDPWS (Micro DPWS) is designed to run on deeply embedded devices with only tens of kB RAM and ROM and thus enables seamless connectivity of deeply embedded devices and resource richer devices.

Most of you may already know the emerging 6LoWPAN (IPv6 over Low power Wireless Personal Area Networks) protocols, pushing IPv6 based communication also down to wireless sensor networks. In the IETF, there are working groups like 6LoWAPP and CORE that are focusing design and development of application layer protocols on top of 6LoWPAN. One approach is of course usage of DPWS ;). There is an Internet-Draft at IETF 6LoWAPP and CORE, discussing this topic of DPWS for 6LoWPAN. So feel free to read the I-D and give feedback!
