ASTAIZA HOYOS, Evelio; BERMUDEZ OROZCO, Héctor Fabio  and  TRUJILLO DAVILA, Dora Lucia. access point Selection in 802.11 Wireless Networks Guaranteeing Minimum QoS. ing.cienc. [online]. 2014, vol.10, n.20, pp.115-137. ISSN 1794-9165.

In this paper we present the research results that conducted to address the problem of associating a user to a wireless access point (AP) in a multicell 802.11 network in which service a large number of users, each user selfishly is connected to the access point that allows it to guarantee a minimum data transfer rate, determined arbitrarily by the user required service. To do this, the interactions are modeled on the wireless network as a non-cooperative game, then the satisfaction equilibrium concept (SE) is introduced and the algorithm to solve the problem of association under this concept is proposed; finally we illustrate the simulation results obtained in a network scenario where, for simplicity and without loss of generality two users and two access points are assumed.

Keywords : noncooperative games; wireless networks; 802.11; quality of service; satisfaction equilibrium; green communications.
