The rapid growth of wireless devices and services exacerbates the problem of spectrum
scarcity in wireless networks. Recently, spectrum auction has emerged as one of the most …

Dynamic spectrum redistribution---under which spectrum owners lease out under-utilized
spectrum to users for financial gain---is an effective way to improve spectrum utilization …

In this paper, we propose a low-complexity auction framework to distribute spectrum in real-
time among a large number of wireless users with dynamic traffic. Our design consists of a …

In recent years, the auction has been widely applied in wireless communications for
spectrum allocation, so that spectrum owners can lease their unutilized spectrum to …

In cognitive radio networks (CRNs), a wireless user with primary access right on a channel
(called primary user) has prioritized access to the channel and the user with secondary …

With the growing deployment of wireless communication technologies, radio spectrum is
becoming a scarce resource. Auctions are believed to be among the most effective tools to …

Spectrum auction, as an ideal solution for the dynamic channel allocation problem, has
become a research hotspot in recent years. Nevertheless, many spectrum auction schemes …

Spectrum auctions, which allow a spectrum owner to sell licenses for signal transmission
over specific bands, can allocate scarce spectrum resources quickly to the users that value …

Auctions provide a platform for licensed spectrum users to trade their underutilized spectrum
with unlicensed users. Existing spectrum auctions either do not apply to the scenarios where …

Spectrum is a critical yet scarce resource and it has been shown that dynamic spectrum
access can significantly improve spectrum utilization. To achieve this, it is important to …
