Achieving Simultaneous Spectrum Utilization and Revenue Improvements in Practical Wireless Spectrum Auctions

Spectrum auctions have been considered a promising approach to improve the efficiency of spectrum use.spectrum reusability is also one of the important properties in spectrum auctions. to handle spectrum reusability, a buyer grouping procedure has been applied in many existing spectrum auction schemes. it is important to note that almost none of the proposed buyer grouping algorithms in the existing works has been specifically designed for spectrum allocation problem. however, buyer grouping in a practical spectrum auction mechanism has its own challenges such as heterogeneity and truthfulness. in this paper, first we illustrate the challenges of buyer grouping in a practical spectrum auction mechanism. then we propose the novel algorithms for spectrum buyer grouping to solve these challenges. by extensive simulations, we show that our proposed algorithms can not only solve the challenges caused by radio spectrum properties but also provide good performance on various auction metrics.
