Ive colored and clustered the nodes myself, by hand, just for that picture
in my site.
For setting the wired nodes in NAM, the best way is to specify the wired
link latency and orientation. There are lots of examples on the /tcl/ex
directory on how to do it.

usingaodv+ help
hi
thanks for the info ..
i rectified the fault by commenting some section and re running
and as you had pointed out i had done a mistake in assigning hier-address to
the wired nodes .
one more doubt
in wired cum wireless scenarios as shown by nam
the wired nodes are seen clustered together.
specifying node positions for wired nodes has no effect.
is there any method to specify where each node should be located exactly in
the nam window?
