With the development of wireless communication technology, the need for bandwidth is
increasing continuously, and the growing need makes wireless spectrum resources more …

Are you involved in designing the next generation of wireless networks? With spectrum
becoming an ever scarcer resource, it is critical that new systems utilize all available …

In this paper, we present an analytical framework to evaluate the effects of multiple spectrum
handoffs on channel utilization and latency performances in cognitive radio (CR) networks …

Wireless networks are expected to support a diverse range of quality of service requirements
and traffic characteristics. This paper undertakes stochastic performance analysis of a …

In this paper, we propose a spectrum allocation framework that jointly considers the Quality-
of-Service (QoS) provisioning for heterogeneous secondary Real-Time (RT) and Non-Real …

The idea of Cognitive Radio (CR) is to share the spectrum between a user called primary,
and a user called secondary. Dynamic Spectrum Access (DSA) is a new spectrum sharing …

We herein analyze the capacity of voice over IP (VoIP) and propose a new method for
finding the minimum detection and false-alarm probabilities to ensure the quality-of-service …

In this paper, we develop an opportunistic spectrum-scheduling scheme for multichannel
cognitive radio networks. In the proposed scheme, the primary user activity and channel …

For protocol and system design in cognitive radio networks (CRNs), it is essential to identify
which system settings or environmental conditions have great impacts on the quality-of …

For a virtual network operator (VNO) of a heterogeneous cognitive radio network (CRN),
finding a channel allocation method that can maximize income while guaranteeing the …
