摘要:

如何将频谱有效地分配给用户并提高提供商的收益是目前研究的热点。针对频谱组合拍卖中提供商收益低的问题,结合用户估值分布不对称的特点,设计了基于随机游走的频谱组合拍卖(RWSCA)机制,以最大化频谱提供商的收益。首先引入了虚拟估值的思想,用随机游走算法在参数空间搜索一组最优参数,并根据参数线性映射买家的估值;然后运行基于虚拟估值的VCG (Vickrey-Clarke-Groves)机制,从而确定赢得拍卖的用户并计算相应的支付金额。理论分析证明了所提机制具有激励相容和个体理性的性质。在频谱组合拍卖仿真实验中,相较于VCG机制,RWSCA机制至少提高16.84%以上提供商收益。

Abstract:

How to allocate spectra to users efficiently and improve the revenue of providers are popular research topics recently. To address the problem of low revenue of providers in spectrum combinatorial auctions, Random Walk for Spectrum Combinatorial Auctions (RWSCA) mechanism was designed to maximize the revenue of spectrum providers by combining the characteristics of asymmetric distribution of user valuations. First, the idea of virtual valuation was introduced, the random walk algorithm was used to search for a set of optimal parameters in the parameter space, and the valuations of buyers were linearly mapped according to the parameters. Then, VCG (Vickrey-Clarke-Groves) mechanism based on virtual valuation was run to determine the users who won the auction and calculate the corresponding payments. Theoretical analysis proves that the proposed mechanism is incentive compatible and individually rational. In spectrum combinatorial auction simulation experiments, the RWSCA mechanism increases the provider’s revenue by at least 16.84%.

Key words: combinatorial auction, spectrum, random walk algorithm, parametric search, virtual valuation
