Hi,
We are working on a Full-duplex project and I am working on the MAC part.
For now, I want to disable the sensing channel mechanism. I mean I want AP and STA start transmission without sensing the channel and don't care if the medium is busy or not. In the wlan_mac_dcf.c, I could not find how I can disable this part. I would be so grateful if you could guide me on this part.
Another question is that, I set the pre_backoff (n_slots) and post_backoff to zero and I expect that AP and STA face a congestion every time. But, STA always wins the medium. What common variable between AP and STA should set with the same value that they both always face congestion?
Best,
Amir

If you want nodes to transmit without regard to the medium state, I would suggest starting with NoMAC. The DCF is inherently half-duplex and schedules Tx events relative to channel activity, including the node's own Tx/Rx events.
