Re: [ns] Error model in wireless simulation



Thanks for your quick response.

However, I need more information. I know how to create an error model but I
don't know how to insert it in the simulation. I just need to know the right
command. But I have not been able to find in the past few weeks! This is
really driving me crazy.

And if it would be all possible I would like to know how the same thing is
done in a normal LAN model.

Thanks in advance,
Lewie

NS is driving me crazy.
