A Game Theoretic Approach to Multi-radio Multi-channel Assignment in Wireless Networks

Abstract. It has been long recognized that the interference among concurrent wireless transmissions plays a crucial role in limiting the performance of wireless networks. Recently, studies indicate that equipping nodes with multiple radios and operating these radios on multiple frequency channels can greatly enhance the capacity of wireless networks. On the other hand, to fully realize the benefits of multi-radio multichannel communication, one may need to design an efficient channel assignment algorithm. In this paper, we study the channel assignment problem by proposing an algorithm that achieves load balancing Nash Equilibrium solution even in a selfish as well as topology-blind environment. Our simulation results also depict the effectiveness of the proposed channel assignment solution.
