Physical Layer Capture (PLC) is a feature present in some 802.11 hardware that enables to receive the stronger signal when two signals collide. This can provide a dramatic improvement to the success of communication because frames lost by the simple definition of collisions can still be received.

Are there plans to incorporate this feature? I know it is present in NS2 and Qualnet.

    We currently don't plan to implement this. But it shouldn't be to complicated to implement for someone who is familiar with this feature. The place where it would have to be implemented at is Decider80211s "processNewSignal()" method. Instead of dropping the signal if "currentSignal" is not empty it could compare their receiving powers and decide which one to receive.

    Thanks for the info Karl, I think this may make a nice graduation assignment.
