now that you have your problem solved, please describe the problem and the
solution in the NS2 wiki, __in your own words__, to help the next NS2 users
that has a similar problem.

Hello Pedro,

Thank you for the help...that was everything i needed.

Just one more thing if you can help you know if it is possible to
load a previously saved layout of my topology in NAM?

Best Regards,

Type of Addresses that a node can have in NS2 (hAddr, ID, iAddr, Handle)?
In NS2, a node can be uniquely identified by several forms 

the "handle" is the otcl name; it refers to an object of the form "_oXXX",
and because of this, it is the only form can be used to directly call
internal instprocs and variables.
the "haddr" is the Hierarchical address, on the form " X.Y.Z"
the "iaddr" is the INTEGER hierarchical address, where the haddr string is
simply ENCODED in a 32 bit integer.
the "id" is the sequential Node ID of the simulator.


In my ns2_shared_procs.tcl "utils" tcl file, I introduce procs for all
possible conversions of each form, using the procs "handle2iaddr",
"handle2haddr", "handle2id", etc.

Feel free to ask further questions if necessary
