Abstract (in Japanese) (See Japanese page) 
(in English) We assumed the following simple scenario; there are three APs, where the cells of all the APs completely overlap and each AP can select multibandwidth channels. In this scenario, a centralized controller coordinates two APs, which jointly select multibandwidth channels. Through game-theoretic analysis, it can be clarified that the coordinated APs are able to select channels more effectively than if each AP independently selects channels. As a results of analyzing the total throughput of the coordinated APs at Nash equilibria, it is improved by at most 80%. Furthermore, we assumed that the coordinated APs cannot only jointly select multibandwidth channels, but also jointly decide the number of stations which each AP admits. Game-theoretic analysis clarified that the maximum value of the total throughput of the coordinated APs increases by considering the admission control. In this paper, in order to take the fairness among stations into account, we propose to use the product of the throughput of each stations as the payoff function. As a result, Nash equilibria exist, and the resources are fairly allocated.
