Dynamic spectrum allocation based on one-band multi-winner auction

In order to improve the effectiveness of traditional auction in DSA(dynamic spectrum allocation) issue in cog-nitive radio networks,a new dynamic spectrum allocation algorithm based on one-band multi-winner auction was pro-posed.Compared with the original greedy algorithm,the new algorithm can achieve better spectrum allocation solutions with lower computational complexity by introducing the multiple greedy strategy.It increases the seller's revenue by im-proving the VCG(vickery-clarke-groves) mechanism,while retaining the dominant strategy incentive compatible prop-erty.In addition,it suppresses the occurrence of collusion effectively.Simulation results show that the algorithm proposed can get spectrum allocation efficiency close to the optimal solution and increase the auction revenue significantly.
