...wlans, the access points (aps) in these networks are often deployed by network non-specialists in an uncoordinated manner, leading to unplanned topology, interference and unsatisfactory throughput performance. we consider in this paper a distributed channel assignment algorithm for uncoordinated wlans, where aps can selfconfigure their operating channels to minimize interference. we propose...
