In a cognitive radio (CR) network, cooperative spectrum sensing plays an important role in ensuring the quality of service (QoS) of primary users (PUs) and improving spectral utilization efficiency.

However, for DSA to become an attractive service reality, it is crucial to ensure also some Quality of Service (QoS) support for the Secondary User (SU) communication. In this paper, we discuss sensing based opportunistic spectrum access approaches, in which PU protection is achieved by a properly organized sensing process and SU communication reconfiguration.

The proposed algorithms provide QoS for cognitive radio systems through the reduction of spectrum handoff probability and improvement of fairness. Performance analysis and simulation results validate the efficiency of the proposed algorithms.

to also ensure some Quality of Service (QoS) support for the Secondary User (SU) commu-nication. In this paper, we propose sensing based opportunistic spectrum access approaches achieving both, protection of the PU, as well as QoS support for the secondary communica-tion. Given the requirements of PU protection and secondary QoS support, we show that

In this paper, a distance-based greedy coloring grouping scheme is proposed to enhance the cost efficiency of two-tier cognitive radio networks. Greedy graph coloring algorithms are preferred for their simplicity, and in many cases they provide efficient solutions [20].Cited by: 1

In this paper, we consider a cognitive radio network with multiple secondary users (SUs). The SU packets in the system can be divided into two categories: SU1 packets and SU2 packets, where SU1 packets have transmission priority over SU2 packets. Considering the absolute priority of the primary users (PUs), the PU packets have the highest priority in the system to transmit.Author: Yuan Zhao, Wuyi Yue

While the required reliability of the sensing process can be expressed in terms of rarely enough overlooking the primary user, we assume that the proper QoS for the secondary user is given by maintaining - with a given confidence level - a minimum bandwidth availability for the secondary user in spite of primary user dynamics.
