Abstract

This  article  describes  the  results  of  the  selection  of  a  access  point  in  802.11  wireless networks multicell, which are currently facing the progressive saturation of the radio spectrum due to overcrowding User. This problem is addressed from the perspective of the theory of noncooperative games where users (transmitter devices) are the players and the possible discrete values of bandwidth defined in the system, strategies that they have to  play,  whereby,  for  the channeling  defined in  802.11g,  and  considering  only  the  nonoverlapping channels, three cases  are  identified  depending  on  the number of channels or amount of bandwidth the user to choose. For game solution concept of Nash Equilibrium (NE) is introduced, the existence of the proposed model is verified and the computational algorithm designed in Matlab mathematical tool proposed, that solves the problem  of  association  under  this  concept.  Particularly,  in this game seeks to maximize the utility for each user, in order  to  find  from  this  perspective,  the  solution  to  the problem raised, in this scenario, it is verified that selected  access  point  from  perspective  of  Nash  equilibrium will  be  the  one  to  present  the  best  channel  conditions gain using the strategy of using the maximum available bandwidth.
