So you mean that queuing of packets and delays in trasmision
because the monitor agent should not be visible in the simulation?
I have not work with the LAN modules of ns, but maybe if you set up
your monitor agent in a LAN type of network you would be able to "sniff
" packets such as in the real scenario.
