Abstract
Multiple characters of spectrum resource bring many challenges to spectrum trading. The demanders may not find the full-matching spectrum resource. Meanwhile, the optimal matching strategy cannot be determined if the demanders have different matching ratios. This chapter proposes an algorithm called HSO-ST (Heterogeneous Service-Oriented Spectrum Trading) with the target of maximum matching number under the priority restriction. This algorithm can satisfy as many secondary users as possible. Compared with other spectrum trading strategies, HSO-ST can greatly improve the spectrum demand-matching ratio.
