There are two choices for point to point links, master/managed and
ad-hoc. On one level ad-hoc seems the obvious one as it avoids the
AP scanning for new clients etc, but ad-hoc connections seem to get
high numbers of collisions under high bi-directional load and so performance
suffers, with master/managed at least one end thinks it is in control.
I suppose that the new 802.11q stuff (I think I have the right letter) which
does things like bulk acks or even turns off wireless level acks would help
but then again does it apply to both modes?
I realise that stated like that this question is not strictly a madwifi
question, but I am implementing these links using madwifi so I am
quite happy to use settings that are madwifi specific.
Have there been any studies of this kind of problem?
It seems odd that there is not a mode designed for this, with just the two
stations, and a ping-pong like protocol where each side sends what it has
to send (to a limit) and then waits for a reply. But then I suppose 802.11
was not really designed for point to point links.
