Cognitive Radio Network (CRN) is regarded as a promising way to address the increasing
demand for wireless channel resources. It solves the channel resource shortage problem by …

This paper studies price-based spectrum access control in cognitive radio networks, which
characterizes network operators' service provisions to delay-sensitive secondary users …

In dynamic spectrum auction, if a buyer locates in a “critical” place, interfering with many
other buyers, its occupancy of the spectrum may deprive many others the transmission …

To match wireless users' soaring traffic demand, spectrum regulators are considering
allocating additional spectrum to the wireless market. There are two major directions for the …

Market based spectrum trading has been extensively studied to realize efficient spectrum
utilization in cognitive radio networks (CRNs). In this paper, we utilize the concept of …

Public regulatory agencies have traditionally assigned radio-electric spectrum in a static
way. This has led to an almost fully assigned but sparsely and unevenly used spectrum, in …

Recent initiatives allow cellular providers to offer spot service of their licensed spectrum,
paving the way to dynamic secondary spectrum markets. This paper characterizes market …

We investigate a spectrum oligopoly market where each primary seeks to sell its channel to
a secondary. Transmission rate of a channel evolves randomly. Each primary needs to …

This paper characterizes the outcomes of secondary spectrum markets when multiple
providers compete for secondary demand. We study a competition model in which each …

In this paper, observing the information asymmetry phenomenon among multiple secondary
users (SUs) spectrum sharing, we analyze the hierarchical decision-making and the …
