[ns] trace analysis

[Vijai Kalyan]

Hi Laura,

The explanation for these is on Griswold's page as well :) You are
looking at the "old wireless formats". However if you want more
detail, try out the files in $ns_dir/ns-2.27/trace especially
{cmu-trace.h, cmu-trace.cc} which specify and implement the methods
for tracing. You might want to look at the functions format and then
format_mac_common ... etc.

I am writing a trace parser lib in java (incomplete ... but I am
working on it) which you might want to have a look at.

hth,

regards,

p.s Explanation for the trace stmts is below ...
