Abstract
Designing and managing wireless networks is challenging for many
reasons. Two of the most crucial in 802.11 wireless networks are:
(a) variable per-user channel quality and (b) unplanned, ad-hoc deployment
of the Access Points (APs). Regarding (a), a typical consequence
is the selection, for each user, of a different bit-rate, based on
the channel quality. This in turn causes the so-called performance
“anomaly”, where the users with lower bit-rate transmit for most of
the time, causing the higher bit-rate users to receive less time for
transmission (air time). Regarding (b), an important issue is managing
interference. This can be mitigated by selecting different channels
for neighbouring APs, but needs to be carried out in a decentralised
way because often APs belong to different administrative domains, or
communication between APs is unfeasible. Tools for managing unplanned
deployment are also becoming important for other small cell
networks, such as femtocell networks, where decentralised allocation
of scrambling codes is a key task.
