I wl suggest use NS3 for such metrics .

You can use a text processing language such as awk in oder to extract information from NS-2 trace files. I recommend the tutorial "NS by example". You can find it in this link:

I hope it helps.  

you can use the simple grep command extract following values (if you know the wireless trace format otherwise use awk script)

joseph jude : I want to know if I need to make any changes with awk attached  for my trace file? I have a trace file.Can anyone help me with the awk script for it?

Thanks everyone for your valuable suggestions. I really appreciate it.

awk script is helpful.

You should adapt the AWK script to your trace file (It's not always the same)

Is there any diffrence in NS3 trace files to NS2  trace files. Can I use the same awk script in NS2 for NS3 trace file?
