The FCC recently issued the regulatory rules for cognitive radio use of the TV white space
spectrum. These new rules provide an opportunity but they also introduce a number of …

Efficient and reliable subcarrier power allocation in orthogonal frequency-division
multiplexing (OFDM)-based cognitive radio networks is a challenging problem. Traditional …

We consider the problem of optimal channel access to provide quality of service (QoS) for
data transmission in cognitive vehicular networks. In such a network, the vehicular nodes …

The deployment of cognitive radio networks enables efficient spectrum sharing and
opportunistic spectrum access. It also presents new challenges to the classical problem of …

Dynamic allocation of spectrum prior to transmission is an important feature for next
generation wireless networks. In this work, we develop and analyze a model for dynamic …

As wireless systems continue to proliferate, interference management is becoming a
concern in both military and commercial domains. This paper introduces a novel cognitive …

In common models of cognitive radio networks (CRNs), priority in spectrum access of
primary users (PUs) must be guaranteed, but the quality of service (QoS) for secondary …

We develop a novel design framework for dynamic distributed spectrum sharing among
secondary users (SUs), who adjust their power levels to compete for spectrum opportunities …

Cognitive radio (CR) is found to be an emerging key for efficient spectrum utilization. In this
paper, spectrum sharing among service providers with the help of cognitive radio has been …

Cognitive radio (CR) network allows fast deployment of wireless technologies to utilize
spectrum channels, all with minimal impact on existing primary users. Another challenge in …
