We have finally made it to publish our Efficient XML Interchange (EXI) parser as Open Source. The implementation is called WS4D-uEXI. The ‘u’ stands for ‘micro’ and yes, this means it has really small footprint. uEXI is designed to run on WSN/6LoWPAN mote class devices with only tens of kB RAM and ROM. You will find some more information, documentation and of course also the code on the WS4D-uEXI project website at Google Code. Fell free to join the project and contribute!

The PipesBox team consists of Jan Krog (Dipl.-Ing. Business Administration and Engineering), Pia Ziegan (B. A. Business Sciences) and Elmar Zeeb (Dipl.-Inf.). We want to establish PipesBox as an essential tool in the building and home automation market for mixing together various application domains and technologies to create heterogeneous applications. We are heading for small and medium installations, where the complexity of existing technologies makes installations currently not viable. Our key motivation is ease of use. We want to dramatically simplify the creation of building and home automation applications. With PipesBox a typical electrician or a user should be able to create and install customized applications.
We also want to address the DIY and Maker communities. Thus we want to base PipesBox on an Open Source Software model, so you can try out and extend PipesBox easily. We will soon publish more details and a roadmap of technical milestones that we want to achieve during the following months. We will use ws4d.org to publish technical details about the current developments of PipesBox and also instructions for DIY projects. So stay tuned and watch out for more news!

We have assembled a brand new demo for our booth at the CEBIT 2012 in Hannover. The demo is based on our well-known Smart Window Demo, but now includes NFC technology to make the system more secure. The video below shows the different flavors we have integrated in the demonstrator. Feel free to join us at our CEBIT booth and watch the demo live!
The 83rd IETF Meeting in Paris is approaching (March 25-30, 2012). Of course, WS4D will be there to contribute in the IoT activities of the IETF (6LoWPAN, CoAP and RPL). Feel free to contact us and meet us there!
We will be at all the three major IoT events in Paris:
At CeBIT 2012 in Hannover, Germany, the ITEA 2 project (http://www.uservices.de/) is going to showcase the easy creation of mobile services. You will be able to have a hands-on with the uService editor, create your own mobile app and share it with other people. Everybody can do that!
The CeBIT is world’s largest and most international computer expo. Please feel free to visit the uService booth at Hall 9, Stand F34 from March 6th to 10th. We look forward to see you there!
The uService project has been funded by the German Federal Ministry of Education and Research under contract number 01—S0902F. German partners in this project are: Communology, DFKI (German Research Center for Artificial Intelligence), DLZ (Deutsches Lauftherapiezentrum), Orga Systems, Safran Morpho, University of Rostock.
Short project description
The uService project investigates the turn of mobile users into service super prosumers in order to benefit from the vast number of potential mobile services. These services can be consumed remotely by other users, in a simple way, with only their mobile devices. Mobile-to-mobile provision of this type of user-generated mobile services implies millions of potential sources with valuable information for the same amount of potential users.
Due to the particular challenge of the mobile environment, where device resources, interaction possibilities and user attention are much more restricted compared to the fixed, traditional Web environment, uService proposes a new way to look at mobile information services in order to solve this problem and deliver services that all users are expecting – above all the non-technical users. In the uService project, this type of service is called micro service or uService. These services are small, sharply focused applications with their own graphical user interface, which allow users to obtain and provide information – like opinions, recommendation, location or speed – to fellow mobile users.

For the 3rd time, the TeKoMed-Workshop will be held in Lübeck. This year it will be a two days event from 7th to 8th of November 2012. Objective of the workshop is the usage of Service-oriented principles in the domain of medical devices, mainly focusing on device integration in medical institutions like for example hospitals. Of course, everybody is invited to participate! Find more informations on the workshop website.
The scope of the SOCNE workshop is on not only on SOAs in general, but also on (resource constrained) device centric environments, including H2M and M2M scenarios. And of course the REST folk is welcome as well :).
May we introduce? User CoAP, CoAP user. The Constrained Application Protocol (CoAP) is an exciting emerging protocol defined by the IETF CoRE WG, currently in the state of an Internet Draft. To put things short, CoAP is supposed to create an alternative to HTTP for RESTful APIs on highly resource-constrained devices. While HTTP usually bases on TCP, CoAP defines rudimentary reliability features so you can run it on UDP and therefore save a lot of protocol overhead that inherently comes with TCP.Now that you have an idea of what CoAP is (if you hadn’t already) we want to share our latest efforts on implementing CoAP. WS4D-JCoAP is supposed to be the first (as far as we know) feature complete CoAP implementation in Java. By this time, we managed to implement a simple CoAP Client application. Within the next days and weeks, we plan to implement a higher-level connection API supporting automatic retransmission and recognition of duplicate messages as well as the whole server side.If you are curious right now or want to support us, check out the google code repository. Have fun!
