We study auction mechanisms for sharing spectrum among a group of users, subject to a
constraint on the interference temperature at a measurement point. The users access the …

We consider a spectrum sharing problem in which each wireless transmitter can select a
single channel from a set of available channels, along with the transmission power. An …

We study a sequential auction for sharing a wireless resource (bandwidth or power) among
competing transmitters. The resource is assumed to be managed by a spectrum broker …

The concept of dynamic spectrum access will allow the radio spectrum to be traded in a
market like scenario allowing wireless service providers (WSPs) to lease chunks of spectrum …

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 …

Cognitive radio (CR) is a promising paradigm to achieve efficient utilization of the limited
spectrum resource by allowing the unlicensed users to access the licensed spectrum, and …

There is a need for new spectrum access protocols that are opportunistic, flexible and
efficient, yet fair. Game theory provides a framework for analyzing spectrum access, a …

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 …

In the future, we can expect to see more dynamic service offerings and profiles, as users
move from long-term service provider agreements to more opportunistic service models …

In this article, we discuss distributed resource allocation schemes in which each transmitter
determines its allocation autonomously, based on the exchange of interference prices …
