[ns] How acess the protocol agent of a mobil node

[Olivier Berho]

Hi all.

I would like to know if someone can explain me how sould I do to get an 
access of the protocol agent of a mobile node.
The mobile node I use is declared in this way :

set val(adhocRouting)   AODV
.
.
.
$ns_ node-config -adhocRouting $val(adhocRouting) \
.
.
.

How could I do to get the "name" of that  variable in order to use some 
methods I have develop in the body of the protocol AODV ?

Thanks a lot.

Olivier.
