Abstract
By combining the features of CSMA and TDMA,
fully decentralised WLAN MAC schemes have recently been proposed
that converge to collision-free schedules. In this paper we
describe a MAC with optimal long-run throughput that is almost
decentralised. We then design two scheme that are practically
realisable, decentralised approximations of this optimal scheme
and operate with different amounts of sensing information. We
achieve this by (1) introducing learning algorithms that can
substantially speed up convergence to collision free operation;
(2) developing a decentralised schedule length adaptation scheme
that provides long-run fair (uniform) access to the medium
while maintaining collision-free access for arbitrary numbers of
