[ns] Trace Analyzer
Hello everybody, I'm making some simulations, and i 'll need to analyze. So I have been searching trace analyzers, and I wanted to know if you could recommend some trace analyzer that calculates the total average delay. I hope you can help me. thank you!

Try defining the process this way:
proc discover_ferry { src dst now index } {
global ns_ node_
...
...
...
}
Hope it helps!

[ns] problem in simulating a wired cum wireless link between two nodes...
Hi Alysson,
Thanks for your time and effort.
However, I would highly appreciate if you could suggest me something to
transfer data between BS or how can I simulate a same kind of topology. My
ultimate aim is to simulate a wireless link between two nodes where the
other side of both the nodes is a wired interface...
Thanking you in anticipation...
Regards,
Samar
