I am working on 802.11e as well. 1. For me the easiest answer was to not worry about the ns trace file, and create my own. I count throughput at the MAC level by printing bytes sent during the simulation, and use a perl script to get the statistics afterward.
2. There are some tools to help you do this. http://www.tkn.tu-berlin.de/research/evalvid/EvalVid/docevalvid.html I am using an H.264 profile, but accuracy isn't important so I just used a mostly equivalent pareto VBR source. I hope this helps! Will Spearman Clemson University > hi all > > I have a very urgent and desperate call for help. I am using NS2-31 and EDCA > patch of TU Berlin, for 802.11e.
