Dear Blog,
My dearest apologies for ignoring you, I have been uncharacteristically quiet for the last year. Luckily, I made a new year resolution to shape up, and pay you due attention. The Internet of Things definitely deserves it. After some time of indecision between this Blog, Google+ and Linkedin, I have decided I’m not much for short posts or tweets, except for announcements. I am going to refocus the Internet of Things blog, and focus on sharing short tutorials and insight into new technology and standards efforts for IoT.
2011 was an incredible year in the IoT industry and at Sensinode. We put a huge effort into driving IPv6 and Web technology for the community with efforts like ZigBee IP, SEP2.0, IETF CoRE and ETSI M2M, which are finally showing results. In 4Q/2011 Sensinode launched a whole new solution called NanoServices for efficient IoT web services end-to-end, and we’re extremely excited about it.

Ubi Summer School – Apply by March 15th
Last summer I had the pleasure to teach a workshop on embedded Internet technology organized in Oulu, Finland – Sensinode’s headquarters is located in the same city. We had a great set of students, and did some of the worlds first CoAP implementations together.
At the end of May the Ubi Summer School will be held again, and I will be teaching a totally new course on embedded web services. This will concentrate on the web architecture, and applying it to M2M networks using the new IETF CoAP, W3C EXI and other leading technologies. There is still room left, so apply now! By the way, looks like the students had a lot of fun last year (but don’t tell that to your boss or professor 
).

Webinar on Embedded Web Services
Yesterday I presented an IPSO Webinar together with Gilman Tolle (Cisco) on Embedded Web Services. Like the other IPSO Webinars, this is available as a recorded Webex event with both voice, slides and the resulting Q&A session.
In the Webinar I cover the web architrecture and how it is being extended for M2M applications on constrained devices and networks. The IETF CoRE standardization effort and an overview of the Constrained Application Protocol (CoAP) are included. This is followed by a great Smart Energy example and a tutorial on Efficient XML Interchange (EXI) technology by Gilman.
In December IEEE Wireless Communiation published an article I wrote on Embedded Web Services as well, available here for IEEE Xplore subscribers.
We are currently working on an IPSO White Paper on embedded web services, so keep your eyes open.
2010 in review
Here is a handy summary of the “On the Internet of Things” blog in 2010, thanks to all my readers, I wish everyone a successful 2011!
The Blog-Health-o-Meter™ reads Fresher than ever.
Crunchy numbers
The average container ship can carry about 4,500 containers. This blog was viewed about 19,000 times in 2010. If each view were a shipping container, your blog would have filled about 4 fully loaded ships.
In 2010, there were 10 new posts, growing the total archive of this blog to 26 posts. There were 3 pictures uploaded, taking up a total of 8mb.
The busiest day of the year was May 11th with 165 views. The most popular post that day was ETSI M2M Standardization.
Where did they come from?
The top referring sites in 2010 were sensinode.com, 6lowpan.net, readwriteweb.com, freaklabs.org, and wsnbuzz.com.
Some visitors came searching, mostly for zach shelby, zigbee ip, 6lowapp, 6lowpan vs zigbee, and etsi m2m.

UBI Challenge 2010
Do you have a brilliant idea for a ubiquitous application? How does access to the worlds most advanced urban ubicom infrastructure and financial support sound?
The 1st International Open Ubiquitous City Challenge (“UBI Challenge” for short) challenges the global R&D community to design, implement, deploy end evaluate novel applications and services in real-world setting in the City of Oulu, Finland.
In addition to public interactive displays, an open WiFi infrstructure, and BT access points, Oulu has deployed the world’s first city-wide 6LoWPAN infrastructure using Sensinode’s NanoRouter products. See an infrastructure overview here.

IETF Maastricht
Greetings from pleasant Maastricht, where the 78th IETF is being held this week. A lot of exciting things are happening on the wireless embedded Internet! Here is a crash course:
The 6LoWPAN WG is finishing its main objectives of finishing the new Header Compression [draft-ietf-6lowpan-hc] and Neighbor Discovery [draft-ietf-6lowpan-nd] optimizations. We expect both drafts to start the proposed standard process soon. Samita Chakrabarti and I will be releasing a short white paper on the updated 6LoWPAN ND for the IPSO Alliance soon.
The new CoRE WG held its second meeting with great progress. In just 4 months a stable version of the Constrained Application Protocol (CoAP) [draft-ietf-core-coap] was developed, along with 10+ interoperable implementations at Plugfest events held this week. Anyone can participate, see the CoRE Plugfest page.
The ROLL WG is currently in progress, with a major milestone being achieved with the completion of last call on the Ripple (RPL) routing protocol [draft-ietf-roll-rpl]. Work is ongoing to complete the security and route metric specifications.
Smart Grid is a hot topic in the energy and communication industries, and the IETF has been active in supporting the energy industry with information on the use of IP. The IETF has a Smart Power interest group for all interested.
See you in Beijing!
CoAP-01 released, ready for a Plugfest?
Yesterday we released version -01 of the Constrained Application Protocol in the IETF. This new version is now a complete and stable specification based on a huge amount of work in the CoRE WG which closed 14 tickets, 10 intermediate drafts and did a lot of implementation testing. The draft is now available at:
A Plugfest is being organized at the upcoming IETF in Maastricht, Netherlands at the end of July for CoAP. The Plugfest is open for anybody to participate in, either on-site if you are attending the IETF, or remotely over the IPv6 or IPv4 Internet.This is an exciting step in realizing the Embedded Web, so do a little coding and get involved! Plugfest information available here:
