On October 17th, the International Workshop on Internet of Things Technology and Architectures (IoTech) was held in Valencia/Spain, co-located with the IEEE MASS conference. The objectives of the workshop read like the who-is-who of several WS4D efforts: IPv6, 6LoWPAN, RPL, CoAP, EXI , IEEE 802.15.4, IoT, WSN etc. So also WS4D joined the IoTech and presented the SOAP-over-CoAP approach. But you might find other things among the presentations.
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…
In January, the Internet Architecture Board announced the ‘Interconnecting Smart Objects with the Internet Workshop‘ to be held in conjunction with the IETF80 in Prague. While the workshop requires a selection of participants, the additional held ‘Tutorial on Interconnecting Smart Objects with the Internet’ is open for everyone. WS4D will join both the workshop and the tutorial. So feel free to join the tutorial and meet the strange IETF folk in Prague!
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.
This is nerdy! We will present our SpO2 sensor running WS4D-uDPWS over 6LoWPAN on an AVR Raven at Cebit 2011 in Hannover. Here is the preview:
On Friday the 26th of November the developer of uDPWS, Christian Lerche, received the “Professor Dr. Werner Petersen” award 2010 for his master thesis. A main outcome of his master thesis was the uDPWS Stack. Every year, the Werner Petersen award goes to the best master and diploma theses in the north of Germany. The award carries a 1000 Euro prize and is supported by the VDE, the VDI (The Association of German Engineers) and the “Professor Dr. Werner Petersen-Stiftung”. Congratulations!
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!
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.
