I m still waiting for reply on ........
Thanks a lot, awk script for throughput is working fine but for jitter
it is creating an error
awk: jitter.awk:69: (FILENAME=AODV-RENO-S2-PT0-0.tr FNR=586509) fatal:
division by zero attempted
Actually I have done my simulation of 720 files and it took around two
months with old format it is now not possible to do the simulation of
720 files again since I have shortage of time to submit my work. I hope
you can understand. It is now requested you to please modify the new awk
scripts to old format I'll be obliged to you. I have 3 Routing protocol
DSDV, AODV& DSR I got an awk script but it shows the result so strange
i-e Packet Delivery Ratio for DSR is much much low than DSDV & AODV .
please help me in this regard
I'll be grateful to you.
Thanks & Regards
