Spectrum Allocation Strategy Based on QoS Grading in Cognitive Radio
Hao Lu · Jisuanji gongcheng · 2012
In order to improve the system throughput in cognitive radio and ensure the fairness of spectrum allocation,this paper proposes a spectrum allocation strategy based on Quality of Service(QoS) grading in cognitive radio.It constructs a comprehensive decision model which can discriminate the cognitive users’ QoS level according to their business types.It employs the spectrum allocation for cognitive customers combined with Collaborative Max Sum Bandwidth(CMSB) algorithm.Simulation experimental results demonstrate that the proposed spectrum allocation strategy can meet the QoS demands of cognitive users,and ensure the higher system throughput and access fairness.
