[ns] about traffic parameters

[vin]

Hi,
I have some problems with modifying some traffic parameters on AODV =
routing,
I want to create  a video traffic flow from a node to another node,
and the time of this flow is 10 seconds,
and similarly the time of voice flow is 5 seconds.
How do I configure because cbrgen.tcl can not control something about =
flow?
And how do I know if this flow is succesful (i.e the destination does =
not move during 10 or 5 seconds)?
In addition,
I want the speed of a node is between 9 and 11 m/s,
and pause time is between 0.1 and 2 sec,
but the command setdest.exe only can control maximum speed and average =
pause time.
How do I configure these parameters?
Thanks for your help.
