Channel assignment has been extensively studied in wireless network such as cellular network, with the appearance of the new multi-radio multi-channel network such as wireless mesh network and cognitive radio network, channel assignment in such network has been a hot research topic again. In this paper, we use game theory to study the channel assignment problem, we model channel assignment in multi-radio multi-channel network as a non-cooperative game, we define a utility function that consider the channel load-balance and fairness among players and thus build up the channel assignment game model, based on the model we propose a novel channel assignment algorithm with fairness and load-balance based on the model. Finally we evaluate the proposed model and algorithm, the simulation results show the model can achieve in fairness among the players and load balance of the channel.
