I am doing some experiments comparing the performance of wireless under 3 different cases:

(i) without media sensing (carrier sensing).
(ii) with media sensing but no RTS/CTS
(iii) with media sensing and RTS/CTS

I know RTS/CTS can be controlled by
iwconfig interface rts {N|auto|fixed|off}

However, what about media sensing? Can it be disabled? If yes, how?
