Thank you for your soon reply. I've already tried exactly the same code that
you suggest for the IBSS case. It compiles ok, but it fails when is executed.
I've been doing some tries and the failing line of code is the pointer
definition:

Ptr<WifiRemoteStationManager> nodeStationManager =
     DynamicCast<WifiNetDevice>(staDevs.Get (i))->GetRemoteStationManager ();

I must confess that I haven't neither worked win IBSS much, but I guessed it
would be applied in the same way as for the BSS mode.

Any help will be welcome.

Thanks!
