Re: [ns] How to create trace files?
Dear Adnan
When dealing with video in data networks, people usually use video sequence
files which
includes the sequence of numbers meaning the generated bytes at each frame.
A frame can be one of the I,P,B pictures when you use MPEG series.
You may have those sequence files already. In your case you need obtain
video sequence file of different coded rates. And please refer to the
description of
format of tracefile in NS manual. The format of tracefile is very simple and
you can code
it by yourself. You may use different time spacing rather than 1/30 sec,
normal case.
If you have any problem in coding, you can search established codes in this
mailing list by
keyword search in NS2 homepage.
