Dynamic spectrum auction has been considered as one of potential approaches on spectrum allocation in cognitive radio networks. As an modified version of traditional static or quasi-static spectrum auction, dynamic spectrum auction should not only increase the auction revenue of the owner of spectrum, but also improve spectrum utilization on fine time granularity. The authors propose a Dynamic Spectrum auction algorithm with Time Optimization (DSA-TO) in an 802.22 network. First, the effects of auction period on auction revenue and spectrum utilization are discussed and optimized. Then they give a complete spectrum auction algorithm where an adaptive reserve price is used to balance the revenue and utilization of spectrum auction.
