On the Internet of Things

The IETF approved a new working group today called Constrained RESTful Environments (CoRE). This new group aims at specifying a RESTful web service protocol for even the most constrained embedded devices and networks. CoRE will be a major enabler for all kinds of sensor network, M2M and other Internet of Things applications!

A very early Internet-Draft on the Constrained Application Protocol (CoAP) can be found here:

A bit of history behind this group. While writing 6LoWPAN: The Wireless Embedded Internet we noticed with Carsten Bormann that embedded web services is one of the key missing components for realizing the Internet of Things. The EU project SENSEI noticed very much the same thing, and has developed an architecture and testbed for integrating Smart Objects into the web using a resource model. These together with the tremendous need for related solutions in the energy industry (e.g. Smart Energy 2.0) kicked us into action last summer at the IETF in Stockholm with an interest group called 6lowapp. This produced a tremendous amount of interest, a large number of Internet-Draft submissions and finally resulted in this new WG!  Looking forward to the next year.

The book exercises have (finally) been released at the 6LoWPAN: The Wireless Embedded Internet website. This slide set includes an overview of embedded technology typically used in the Wireless Embedded Internet, an overview of embedded development and a short tutorial on Contiki. The slides currently include a small number of Contiki related exercises. Both the Contiki overview and exercises will be continuously updated, so check for updates!
