This is an initial commit of an implementation of the Chameleon

Browse source 
architecture for the Rime stack for Contiki. The Chameleon
architecture separates the header processing from the Rime protocol
logic. Instead of having each protocol create its own part of the
packet header, protocols use packet attributes. Before sending a
packet, a special Chameleon header processing module creates a packet
header from the packet attributes. The same Chameleon module parses
incoming packets and creates packet attributes from the header.

The details are in our SenSys 2007 paper:

Adam Dunkels, Fredrik Osterlind, Zhitao He. An Adaptive Communication
Architecture for Wireless Sensor Networks. In Proceedings of the Fifth
ACM Conference on Networked Embedded Sensor Systems (SenSys 2007),
Sydney, Australia, November 2007.

http://www.sics.se/~adam/dunkels07adaptive.pdf

This is a rewrite of the code that was developed for the paper.
