Auction is an effective method of allocating scarce spectrum resources in cognitive radio
networks, where the primary users are sellers and the secondary users are buyers. In order …

Cognitive radio improves spectrum efficiency and mitigates spectrum scarcity by allowing
cognitive users to opportunistically access idle chunks of the spectrum owned by licensed …

In this letter we propose an auction theory based algorithm for throughput maximizing
scheduling in centralized cognitive radio networks (CRN). In the considered CRN scheme, a …

This paper proposes a new spectrum allocation scheme based on detection probability of
cognitive users. This new scheme takes a look at a cognitive radio network system …

The problem of dynamic spectrum allocation for participatory cognitive radio (CR) networks
is modeled using an auction-based mechanism, where the fusion center (FC) acts as an …

Dynamic spectrum leasing (DSL) was proposed recently as a new paradigm for dynamic
spectrum sharing (DSS) in cognitive radio networks (CRN's). In this paper, we propose a …

In order to improve auction effectiveness in dynamic spectrum assignment (DSA), a new
assignment scheme based on FADM (fast auction with multiple goods and multiple winners) …

In this work we investigate an auction mechanism for sharing available wireless bandwidth
among competing cognitive radios. The bandwidth under consideration may be either in an …

We study how truthfulness can be enforced as a dominant strategy when a number of
secondary cognitive radios participate in an online expiring spectrum sharing auction, held …

Market mechanisms have been exploited as important means for spectrum acquisition and
access in cognitive radio networks. In this paper, we propose a two-tier market for …
