Hi,
I am just a little confused. If some one send a RTS and all nodes
update their NAV based on the data packted that is to be tx (plus the
ACK) and the RTS fails (corruption/collision). Do the RTS listening
nodes (and potentially CTS listening if the CTS collides) wait till the
end of their NAV to re-contend?

Also, separately, in a normal CSMA/CA if you wake up and sense nothing,
you dont immediately transmit something? I read somewhere an immediate
tx. and other places a wait period chosen uniformaly from the current
CW.

and finally, if you do sense something- how do you decide when to next
sense the medium (assuming there was no RTS or you missed the RTS )?

I would really appreciate some expert replies or suggestions on where
to ask this from a more qualified audience in this particular aspect?

Thankyou.
