So you missed the earlier comment from someone who has problems with
wifi working reliably due to overloading?
It would have been hard for me to miss it since I was the one that
made it. ;-)
Oh :)
However, it only takes two users streaming files between themselves to
kill connectivity for everyone else.
There is nothing preventing fair-share routing/filtering. This is
actually a common filter that both Linux and BSD kernels have
available in their IP filtering subsystems. In fact, there is a lot
of research on various different "fairness" algorithms. This is one
of the things that open-source will almost certainly do better since
there are tons of competing ideas and tons of research papers.
Certainly.
Also.
There is nothing stopping any users choosing to utterly ignore the
fair-share algorithms.
If enough users - and it takes a small proportion - do, then the whole
thing collapses.
The other problem is that fair share algorithms can only work out to the
distance to which the users can recieve individual signals.
However, the signals from distant stations still interfere, and increase
the channel noise level, reducing range.
With planned networks, this is all managed.
With unplanned networks, it could in principle auto-configure, but only
if everyone implements the same fairness protocol.
