Thanks for all the scripts that all of you have send to this list, they have
been very interesting for my work. Anyway, I have a doubt.
I use new wireless trace format, but I can't diference between routing and
information packets.
When I use DSR, routing packet is the one with "RTR" word, isn't it? But what
is the diference between have -It DSR or -It cbr? In this scripts only "RTR"
with -It DSR are taken on acount in routing packet sum.
When I use DSDV, what is the diference between message and cbr words?
I have no found any documentation about it, so I'm sorry about this questions
Thanks in advance, Mikel

About the awk that calculate Packet Delivery Fraction , Normalize routing
load, End to End delay and drop packets and Routing Load(overhead) its valid
for new trace only. So you can modify the parameters used in the awk script
only or when there ia available time I will modfy it for you.
Lastly I advice you to use new trace format using TCL command in your TCL
file :
$ns_ use-newtrace
you will get the trace file in new fashion
