Hello Andre,

Look in mac-802_11.cc for

static MAC_MIB MMIB =
{
	MAC_RTSThreshold , MAC_ShortRetryLimit,
	MAC_LongRetryLimit, MAC_FragmentationThreshold,
	MAC_MaxTransmitMSDULifetime, MAC_MaxReceiveLifetime,
	0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0
};

The value 'MAC_RTSThreshold' determines whether to use or not RTS/CTS
mechanism depending on the packet size. If you substitute it for a '0'
then you will always use the RTS/CTS mechanism.
