Carrier Sensing Threshold (CCA Threshold) test scenarios

[bartek....@gmail.com]

Hi all,
I am a new user of ns-3 simulator. I need some advice and 4,5 test scenarios for testing an influence of carrier sensing threshold on behavior performance of IEEE 802.11aa networks.

Regards,

Hello, to my knowledge, there is no support in ns-3 for 802.11aa, so as
a first step, one might review the scenarios in a published paper (e.g.
http://www.sigcomm.org/sites/default/files/ccr/papers/2014/January/2567561-2567567.pdf)
and then work on the ns-3 extensions necessary to duplicate the
scenarios shown in the figures (e.g. Figure 1 of that paper) and then
later, the results in that paper.

As for how to get started, I suggest to thoroughly review the code and
operation of existing wifi model and test code (in the src/wifi
directory).  Using a debugger like gdb to step through the operation, or
using ns-3 logging, are two good ways to learn how it presently works. 
The wifi module documentation is here:
