I finally found the time to clean up the code for DES-Chan, the channel assignment framework, and the algorithms based on it. Work on the framework started already 4 years ago and has been grown steadily due to the great work of a changing team of students and co-workers. It is also the foundation for most experiments in my dissertation work.
The code for the framework, the distributed channel assignment algorithms, and the ETX daemon for neighbor discovery in a wireless mesh network are now part of the DES-Testbed repositories at github. Thanks again to everybody who has contributed so far!
