In this paper, the authors study how users in a multi-channel wireless network can select frequency channels in a distributed and autonomous manner for transmitting their multimedia data such that their utilities (multimedia qualities) are maximized. In the multi-user network, the users' transmission actions (the channel selection) are coupled by their mutual interference. However, most of the current channel selection solutions respond myopically to the aggregate interference experienced in each frequency channel. Instead, it is important to develop accurate prediction models which enable multimedia users to predict the interference from the other users and, based on the models, foresightedly optimize their decisions to maximize multimedia qualities.
