Spectrum decision is the ability of a cognitive radio (CR) to select the best available
spectrum band to satisfy secondary users'(SUs') quality of service (QoS) requirements …

With the rapid development of wireless communication, the scarcity of spectrum becomes
more and more prominent. Cognitive radio is proposed to overcome the problem of low …

In cognitive radio (CR) networks, medium access control (MAC) protocols play an important
role to exploit the spectrum opportunities, manage the interference to primary users (PUs) …

The objective of the FARAMIR project is to research and develop techniques for increasing
the radio environmental and spectral awareness of future wireless systems. Radio …

Power control plays significant role in the cognitive network system where secondary users
(SUs) co-exist with primary users (PUs), but the interference due to SUs may affect the …

Medium Access Control (MAC) protocols play an important role in cognitive radio (CR)
networks. In this chapter, we first introduce the challenges in designing CR MAC protocols …

Considering the capacity gain of the secondary system and the capacity loss of the primary
system caused by the newly accessing user, a distributed binary power allocation …

We study a dynamic channel selection framework for cognitive radio networks (CRNs) which
support both delay sensitive and best effort services. Unlike existing works in the literature …
