This talk discusses a new class of channel allocation algorithms that are simple, robust and require no communication between interfering WLANs. These algorithms are provably convergent and yet remarkably efficient under a wide range of network conditions and topologies. Using measurements of performance in a real office environment one interesting observation is that the interference between WLANs is generally channel dependent. This means that a different conflict graph is associated with each channel. This potentially has important implications as the behaviour of many proposed colouring-based algorithms for channel allocation is unclear in this context.
