Hello Daniel,

Thank you, but you didnt say why the solution of simulating a complete
node failure wouldn't work.
I understand that shutting down links is not an option since links don't
exist like i supposed but shouldn't i be able to shut down a node in
wireless like i do in wired scenarios figures?
