The Contiki team is proud to announce the release of version 2.4 of the Contiki operating system! Contiki 2.4 brings a number of new improvements over previous versions, several bugfixes, and an overall improved stability of the system. The low-power wireless MAC protocols have gotten an overhaul, improving power-efficiency and improved collision and interference handling. The COOJA/MSPsim simulation environment has received a significant speedup. Two new experimental platforms are included: the Crossbow MicaZ and the Sensinode CC2430/8051 platform. Many improvements and bugfixes has been made to the uIP code as well as the SICSlowpan implementaion of 6lowpan IPv6-over-802.15.4. See the changelog for full details and go to the download section to download the 2.4 release!

Two upcoming conferences on wireless sensor network research, which should be of interest to many working on Contiki-related projects: the 6th ACM workshop on hot topics on embedded networked sensors (HotEmNets 2010) and the 8th ACM conference on embedded networked sensor systems (SenSys 2010). HotEmNets is a high-caliber workshop for discussing the future of sensor networks research, in light of novel research results. Those interested in participating should submit a five-page paper before February 22 - deadline extended to 1 March 2010 - see the website for information on what to submit. SenSys is a top-tier, highly selective conference for presenting research results on sensor networks. Papers should be submitted by April 8.
A lot of people are using Contiki, developing software for Contiki, testing new protocols or mechanisms with Contiki, porting Contiki to new platforms, and extending Contiki with new functionality. To allow such Contiki-based projects to be accessible to all Contiki users, we have set up a new SourceForge project for new Contiki-based open source projects, dubbed the Contiki projects community

With the help of the Gource source code visualiation tool, here is another nice visualization of the Contiki source code development, from March 2003 to January 2010. For best results, click the full screen button, or watch the YouTube HD version.
One of the characteristic and influential features of Contiki is the use of IP in low-power radio sensor networks and smart object networks. IP-based smart objects are today being standardized through the IETF and made accessible through the IPSO Alliance. As part of this general development, JP Vasseur and me have written a book on IP-based smart object networks with the title Interconnecting Smart Objects with IP - The Next Internet.
The book covers IP-based sensor networks from the link layer and up, and covers network architecture (IPv6, transport, web services, etc), the underlying technology (RPL routing, the 6lowpan IPv6-over-802.15.4 adaptation layer, hardware, software, etc), and applications of IP-based smart objects (the smart grid, industrial automation, home automation, smart cities, etc). The book is scheduled to be available in June 2010, but is already available for preorder from Amazon.com. We have set up a website for the book here.
