Abstract(in English) The increased density of wireless LAN access points (APs) based on IEEE 802.11 standard has induced severe inter-cell interference which severely degrades the performance of the system. In order to mitigate this issue, this paper proposes an efficient network-controlled channel allocation scheme. Based on the channel monitoring results obtained from APs and data traffic amount at each AP, the channel assignment server computes the quasi-optimal frequency channel of each AP in such a way that throughput is maximized. Through numerous simulations with UDP traffic flows, we show that the proposed scheme improves the minimum cell throughput and fairness among throughput of APs.
