The Wireless Embedded Internet Helping the next Billion Nodes onto the Internet


6LoWPAN Book Released

Our 6LoWPAN book has now been released by Wiley. Last week we received the very first copies directly in Japan while at IETF-76. Pre-orders should start arriving any time now to people. At least we are very pleased with the result, so happy reading! For those who would like a preview an excerpt is available on-line:

“6LoWPAN: The Wireless Embedded Internet” – Chapter 1

I will be releasing the book’s companion course slides and exercises very soon here on

News from the 75th IETF

(from On the Internet of Things blog)

Here is some of the latest news from IETF activities related to the Internet of Things:

6LoWPAN - The 6lowpan working group is currently moving four Internet-Drafts towards last call in the standards track (Improved Header Compression, 6LoWPAN Neighbor Discovery) and informational track (Use Cases, Routing Requirements). I presented the latest ND draft, which has good consensus and will be going through a round of technical improvements within 2 weeks. Next the WG is looking to re-charter to continue on subjects such as security, MIBs etc.

ROLL – The roll working group presented the RPL (pronounced “ripple”) routing protocol draft, which has been accepted as an official working group document today. This will be the basis for routing over low-power and lossy networks including 6LoWPAN, which still needs lots of contribution to reach a full solution.

New 6lowapp effort - We held a very successful meeting about applications in resource-constrained networks. About 60-70 people attended presentations from Carsten Bormann, Don Sturek (from Pacific Gas & Electric and ZigBee/IP) along with a set of 2-minute stand-ups. The presentation is available here. The feedback from IETF Area Directors was that there is obvious support, motivation and requirements (and that we are in a hurry) – so start working! A 6lowapp mailing list and wiki page will be coming soon, keep tuned.

There was a great presence at the IETF from IPSO members, who held several meetings during the same week. Thanks to the move of ZigBee and the energy industry towards all-IP smart energy we say many new participants in Stockholm. It is really positive to see the collaboration between the IETF, IPSO, ZigBee and Utilities in this area.



Welcome to, a new site dedicated to The Wireless Embedded Internet. The explosive growth of inexpensive embedded computing technology, combined with low-power wireless standards and new IPv6 technology called 6LoWPAN is enabling the Internet to go where it couldn't before - enabling even the most limited devices to become part of the Internet. The next billion nodes will be on the Internet before we know it.

Stay tuned to for:

  • Tutorials and information about 6LoWPAN and related technology
  • Companion material for the book "6LoWPAN: The Wireless Embedded Internet"
  • Standardization news from the IETF, ETSI M2M, W3C etc.
  • The latest industry updates and news

We are looking for contributions, please get in touch with the authors if interested!
