In many cases, a mobile user has the option of connecting to one of several IEEE 802.11 access points (AP), each using a separate channel. The performance of the user in each AP is determined by the number of other users, as well as by the size of the frame and the physical speed that are being used. We consider the scenario where users could multi-home, that is, divide their traffic among all available access points, based on the performance they get and the price charged. Therefore, they are involved in a non-cooperative game with each other. We convert the problem into a fluid model and show that under a price scheme, which we call the cost price mechanism, the total system performance is maximized, ie the system does not suffer loss of efficiency due to the egoistic dynamics.
