A spectrum auction strategy for multimedia stream in cognitive radio network

Research about multimedia streaming in cognitive radio network has become a hot issue recently. In order to enhance the throughput of real-time multimedia streaming and maximize the utility, we proposes a dynamic spectrum allocation strategy based on Qos-layering and auction theory (QLAS). In this strategy, we classify the secondary users according to the feature of data stream, and choose the optimal channel for every user. When the primary base station receives the access request, it chooses the winner based on auction theory and allocate spectrum to winners. Analysis and simulation result show that, this strategy can guarantee the heterogeneous requirements of heterogeneous SUs and improve the spectrum utilization.
