A Novel Algorithm for Estimation of QoS in Cognitive Radio Using Fuzzy Logic
Nisar A. Lala, Moin Uddin · 2013
Cognitive radio is a technology initiated by many research organizations and academic institutions to raise the spectrum utilization of underutilized spectrum channels through dynamic spectrum access. Quality of service (QoS) provisioning in cognitive radio network is a challenging task due to limited and intermittent availability of the spectrum. In this paper, we have selected three critical parameters; bandwidth, signal strength and bit error rate (BER) to analyze their impact on QoS using fuzzy logic based approach. The simulated results provide the impact analysis of these selected parameters on perceived QoS and open new issues in designing protocol structure for spectrum sensing and management.
