[ns] running multiple simulations.

[wben-jab]

Dear all,

I want to do many simulations using .TCL script with different seed,  
and then clearing the different objects that are created in the  
previous simulations.
Could someone help me whether there is an idea, or giving a link. I  
tried to do as follows, but it executes only the first round. How to  
delete the previous created objects?

for {set i 0} {$i < 10} {incr i} {
      set seed $i;
      exec ns testProtocol.tcl seed
      }


Thanks,
Best Regards.
