Efficient spectrum allocation is becoming more and more important in wireless networking. Auction is believed to be an effective way to address the problem of spectrum shortage, by dynamically redistributing spare channels among service providers. Combinatorial auction gives buyers the freedom to place bids on combinations of channels rather than individual(More)
Dynamic spectrum access (DSA) redistributes spectrum from service providers with spare channels to those in need for them. Existing works on such spectrum exchange mainly focus on double auctions, where an auctioneer centrally enforces a certain spectrum allocation policy. In this paper, we take a different and new perspective, proposing to use matching as(More)
Dynamic spectrum access (DAS) is an efficient way to redistribute spare channels among users. Conventionally, dynamic spectrum access is conducted through (double) spectrum auction, where a third-party auctioneer collects bids from buyers and sellers, and determines the spectrum allocation. Rather than placing bids only on individual channels, combinatorial(More)
