Dynamic spectrum access has become a promising technique to fully utilize the scarce
spectrum resources. However, spectrum allocation schemes with high efficiency and Quality …

Dynamic spectrum access has become a promising approach to fully utilize the scarce
spectrum resources. In this paper, two new dynamic spectrum access schemes for …

Dynamic spectrum access has become a promising approach to fully utilize the scarce
spectrum resources. In a dynamically changing spectrum environment, it is very important to …

Dynamic spectrum access (DSA) is important for spectrum management in the future. DSA
with prioritization for two types of radio systems are presented through analytical formulation …

In order to fully utilize the scarce spectrum resources, with the development of cognitive
radio technologies, dynamic spectrum access becomes a promising approach to increase …

We study two important aspects to make dynamic spectrum access work in practice: the
admission policy of secondary users (SUs) to achieve a certain degree of quality of service …

An efficient and utmost utilization of radio spectrum resources has stimulated the
introduction of what has been termed dynamic spectrum access methodologies and …

In dynamic spectrum access (DSA), secondary users (SUs) dynamically search and access
spectrum bands unused by primary users to communicate. We propose a DSA scheme …

One of the reasons for the limitation of bandwidth in current generation wireless networks is
the spectrum policy of the Federal Communications Commission (FCC). But, with the …

In this paper, we analyze the delay performance of a secondary user (SU) under dynamic
spectrum access. We design simple time-threshold policies for the SU to minimize the …
