Hi everybody.

I need to repeat N times the same scenario but changing the seed.
I tried to put in my .tcl script

set rng [new RNG]
$rng seed <integer number>

changing <integer numer> for every simulation, but the average delay I 
measured is always the same. On the contrary I am sure that should change, 
since the backoff times of my mobile nodes should change.

The other solution could be modifying the 6 values 12345 in double 
RNG::next_seed_[6] in the file rng.cc?????

Please give me some suggestions.

Thank you in advance.
