[ns] Extracting location co-ordinates of node in an ad hoc network

[shshah@cairo.cs.uiuc.edu]

Hi,

I would like to know which object and which members of this object contain
the x and y co-ordinates of a node in an ad hoc network simulation at a
particular instant. 

I would like to periodically record the position using a procedure similar
to the record {} procedure in chapter 8 of Marc Greis' tutorial.
