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

Instead, I achieve the same result by setting the length of the wired links

Hi ns-users,
I learnt that the previous problem can be solved by using 'orient'
method at the link definition. However, this solution is not enough when
defining more complex structures. The next figure shows 4 nodes standing
in the imaginary vertexes of a square, which are all of them connected to
a master node like it is shown in the next picture:

I have the same situation.
I solve it by using the same delay in the real simualtion, and use different
delays just for debugging.

When I do not define the links, the nodes are shown correctly in NAM
(without lines between them), but when I make some of the link definitions
(lines 46-48 of the above code), the structure of the network changes, and
it is shown as a straight line.
I know that I
could manually edit the position of the nodes by clicking on the
Edit/View button in NAM, but I would like to build the structure of the
network automatically for future bigger structures, where it is not
affordable to edit them manually.
How could I solve the problem??
Many thanks in advance,
Regards,
Javi
