[ns] 802.11 Carrier sense
Mon Apr 15 05:16:06 2002
I'm unable to discern exactly when (i.e. where in the 802.11 code) the
first carrier sense before the first RTS for a packet occurs. If the
carrier is found busy at this carrier sense, I would like to be able to
modify the backoff interval after the deferral that follows the busy
carrier sense. Rather than have the station backoff cw_ slot times, I'd
like to have it backoff some other number of slot times.
I do not wish to modify the backoff procedure that is followed after a
collision, however. I want the cw_ doubling, backoff = cw_ number of
slots, etc. to remain as is, in the case of collision.
Could anyone kindly provide me some guidance? Thanks in advance.
