[Ns-developers] a new 802.11 PHY and MAC

[Gavin Holland]

I also have a version that is built on an old code base that may be
of use to the community.  It is built on Josh and David's original
distribution and has fairly detailed interference and channel modeling.
The implementation is described (roughly) in my Mobicom 2001 paper.
http://citeseer.ist.psu.edu/holland01rateadaptive.html.  I've been
meaning to port it to a more recent base but just haven't had the time.

Mathieu, it might be a nice complement to your code.  If it is of 
interest, I would be happy to help migrate the useful bits.  All I 
would need to know is how to post it to the forge.

The current code is distributed under the GPLv2. I will change this to
whatever license is deemed preferable for inclusion in ns2.

The current code contains:
  - mostly untested but should be working 802.11 PHY
  - code to simulate different modulation/FEC types
  - code to handle different rate control algorithms

The MAC you can find in this code is still a work in progress which
means that it does not work, is not expected to work and will change.
Every file is pretty heavily commented so I expect the codebase to be
rather easy to review.

Comments are welcome.

regards,
Mathieu
