认知无线电中基于QoS分级的频谱分配策略
Spectrum Allocation Strategy Based on QoS Grading in Cognitive Radio
摘要
Abstract
In order to improve the system throughput in cognitive radio and ensur 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.关键词
