respected sir.
i designed the senario blow but i donot get any difference for queue type
Droptail and RED
please help me by providing some suggestions. packet loss are same for both.
Blow whole program is kept same only i change between node3 and node 4 to RED

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...

Samar

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!
