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.

The Cooja/MSPsim simulator is now ten times faster than before. Cooja/MSPsim allows Contiki software to be accurately emulated at the cycle level, with detailed emulation of the radio transceiver. With the Timeline view, the radio transceivers of all nodes in the entire network can be simultaneously inspected, providing insights into both the network behavior and network power consumption. The simulation speed is now ten times faster thanks to a recent patch to the part of the Cooja/MSPsim code that integrates the two pieces of software.
