Hi, I already made the same question, i'm using the NIST WiMAX module, and the trace files are hard to analyse. So what i did was to use this method: http://140.116.72.80/~smallko/ns2/tool_en.htm ,made by Chih-Heng, Ke.
With the c++ functions you get 2 files which the default name is "rd" and "sd". This files are easy to analyse, and i'm getting results that "look good", but unfortunately i can't tell if it is reliable method to use, i'm just using, the best thing was to know exactly how to interpert the trace files, but for me, at this moment i don't have time. I already asked in the forum but i got no opinions about the method. kindly, Tiago Junqueira
