Re: [ns] ns/nam: respresentation problem when definingposition-fixed nodes (NEW question)
I have the same situation.
I solve it by using the same delay in the real simualtion, and use different
delays just for debugging.

Re: [ns] ns/nam: respresentation problem when definingposition-fixed nodes (NEW question)
Hi,
Thank your very much for your reply.
It is a good idea, but in my case all the links must have the same delay, so
that is not a possibility.
It is a pity that NAM does not support this facility.
Best regards,
Javier

I' tried to add XY coordinates for wired nodes, but nam doesn't support this
facility.
Instead, I achieve the same result by setting the length of the wired links
via their delay
