[ns] wireless simulation trace file

["Wendy Ng" <wpn2@cornell.edu>]

Hi everyone,

I would like to know whether the new trace file format should be used if I
am doing wireless simulation.  There is the option of calling "$ns_
use-newtrace" to set up new format for wireless tracing (according to NS
Manual 16.1.6).  Apparently, the sample wireless simulation scripts are not
using this option.

Also, when I use the new trace format, I got "2a" for the field "-Ma".  It's
suppose to indicate the duration, so what does that "2a" mean?

Thanks,
Wendy
