Dear Sir,
Don't worry about that, I will help you step by step to get the correct
results, firstly use the attach awk script to extract results from you
simulation output file using the command:
awk -f metrics.awk out.tr
and let me see the results, if its not worked well, there is another soultion..

Subject: Fwd: help me fix this trace
Hii ns-User
I was read in ns mailing list and I found your name in contribute helping other
peoples.
I truly need your help..
I was simulated my tcl script in ns2.30 using new_trace format
I have out.tr then I want to calculate 3 performance metric :
paket delivery ratio, normalized overhead and end to end delay.
I use my awk script to get desire value but I don't know that was not success.
I get this value in my parsing result
send = 8871.00
recv = 0.00
routingpkts = 682.00
PDF = 0.00
NRL = inf
Average e-e delay(ms)= nan
No. of dropped data (packets) = 322
No. of dropped data (bytes) = 171304
I am attach .tr file in my mail, please help me what's wrong..?
why my recv and PDF = 0.00?
My awk script was wrong? or
can you give me correct calculation with my out2.tr in my attachment ?
What meaning of : NRL = inf
Average e-e delay(ms)= nan
thanks for your reply.
