[ns] a loop or a start and stop methods

[Nabila khedimi]

Hi,
I want to execute a ping agent continuously during the simulation, regarding 
the schedular object in NS, is there any the difference between making a 
infinite loop inside the tcl code or define a start and a stop method inside 
the ping agent code(which is a c++ program)
Thanks for help

You need to schedule a tcl proc which: 
a) does ping "send"  
b) reschedule itself for 1 second later

this is a simple 4 line TCL proc!

you can also do this in c++ only by using a timer object, for the same
purpose. This will require recompilation and c++ debugging.
