ACM SenSys is by many considered the most prestigious conference in the area of networked sensor network systems. Contiki has been very visible at SenSys for the past three years: In Boulder, Colorado, USA, November 2006, we presented two papers. In Sydney, Australia, November 2007, we presented a paper, a demonstration, and the best demo award was given to a Contiki-based demonstration. In Rayleigh, North Carolina, USA, November 2008, our poster on uIPv6, the world's smallest compliant IPv6 stack, got the best poster award. Mathilde Durvy and Julien Abeillé from Cisco presented the poster and received the award certificate.

Contiki's Managed Memory Allocator Explained PDF Print E-mail
Developers
Written by Adam Dunkels, Tuesday, 28 October 2008

mmem, Contiki's managed memory allocator, is one of the three dynamic memory allocation mechanisms in Contiki (the other two are the memb block memory allocator and standard C malloc). Unlike malloc, the managed memory allocator ensures that memory fragmentation never occurs. Akiba at Freaklabs has written a lengthy post that describes how Contiki's managed memory allocator works along with a follow-up post that explains how to correctly use the module.

Tutorial: Running Contiki with uIPv6 and SICSlowpan Support on the Atmel Raven PDF Print E-mail
Tutorials
Written by Julien Abeille, Monday, 20 October 2008

Last week we announced uIPv6 and that Contiki is IPv6 Ready. This tutorial explains how to run Contiki with IPv6 and 6lowpan support on Atmel RAVEN evaluation kit (ATAVRRZRAVEN) hardware. We present basic example system architecture and application scenarios, as well as instructions to run more advanced demos.

uIPv6: Contiki is IPv6 Ready PDF Print E-mail

Written by Adam Dunkels, Tuesday, 14 October 2008

Cisco, Atmel, and SICS today announced uIPv6, the world's smallest open source compliant IPv6 stack, for Contiki. uIPv6 passes all the tests required for an IPv6 stack to be called IPv6 Ready and we therefore can use the IPv6 Ready logo on the Contiki web site. uIPv6 has been tested on the Atmel AVR Raven platform and on the x86. We have committed the code to the Contiki CVS and will release the code as part of the upcoming 2.3 release, as well as a snapshot release of the current code planned for tomorrow.

Together with uIPv6, we include an 802.15.4 MAC layer for the Raven platform as well as SICSlowpan, an implementation of the 6lowpan header compression mechanism for IPv6 over 802.15.4.
