Hi, all.

I used to use OPNET to simulate ad-hoc networks.
But, when nodes sense the wireless medium (Carrier Sensing),
OPNET couldn't cumulate the detected signals, I think.
OPNET regards only the latest signal as carrier.
So, when the strength of the latest signal is very weak, 
it may determine the medium is idle even when the other signals are strong.

Is this (still) true?

( By the way, when a node receive signal addressed to it, 
 OPNET can accumulate the other signals as interference.)

Regards.
