Experimental Implementation of Optimal WLAN Channel Selection without Communication

[1] proposed a simple decentralised algorithm for channel allocation that is provably correct and requires no message passing or common administrative control between interfering WLANs. In this paper we implement this algorithm using a standard 802.11 hardware testbed and demonstrate that it does indeed offer the potential for effective channel allocation in realistic environments. This includes environments with complex, spatially varying noise and channel dependent propagation behaviour and with time-varying load.
