The CeBIT 2011 is over and we proudly showed what is possible with the WS4D frameworks. An Pulse/SpO2 sensor using 6LowPAN and a remote controlled window live from the Embedded 2011 were the highlights.
We showed the total lineup from small devices using the uDWPS up to the newest App for Android using the JMEDS Stack.
PipesBox was used to control the window via a twitter API. That was awesome. Feel free to use our open source stacks and get infected by the web service idea and get curious for the CeBIT 2012.
Posted in Conference, DPWS | Comments Off on The CeBIT 2011 is over. Welcome CeBIT 2012.
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…
Background: WS4D participates in the IETF mainly in the 6LoWPAN and CoRE working groups, published I-Ds about DPWS for 6LoWPAN and SOAP over CoAP and has developed WS4D-uDPWS, an Open Source DPWS stack for mote class devices.
Since the movement towards the Internet of Things and Smart Objects is gaining in momentum more and more, WS4D is proud to contribute to this field. Therefore an Internet Draft is published in the active IETF CoRE working group, describing an approach to bind SOAP to the CoAP protocol. Since CoAP is currently in draft state, the SOAP-over-COAP is it of course also. Nevertheless, contributions and feedback to the draft are more than welcome. Find the draft at http://tools.ietf.org/html/draft-moritz-core-soap-over-coap.

This years’ ARTEMIS & ITEA Co-Summit, was held at the ICC, International Convention Center, in Ghent, Belgium. And of course WS4D was there presenting their contribution to the OSAMI project. Beside several cool stuff like OSAMI device integration and remote services for OSGi, in Ghent also the WS4D-uDPWS stack was in action. See the small black box below in the pictures with a prototype consisting of an Atmel AVR Raven and a Corscience SpO2 Sensor. On the Raven board WS4D-uDPWS is running providing a DPWS interface for the SpO2 sensor. And yes, this is DPWS over 6LoWPAN!
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!
