Abstract:
In this paper, we propose an opportunistie spectrum sharing ( OSS ) algorithm with quality-of -service ( QoS) support to coorlinate the spectrum aecess of primary users ( PUs) and secondary users ( SUs)for cognitive radio nelworks ( CRNs). We also analyze its performanee in the presenee of two secondary users(SUs) groups with different terminated-priorities and aeeess-priorities, which are defined to saisly differenlQoS requirements of SUs. In addition, we use a six-dimensional Markov approach to derive system perform.anee , such as SU foreed termination probability, blocking probability and system throughput. Numerieal re.sults show that the QoS requirements of dilerent SUs can be guaranteed in the presence of guaranteeing thecommunieation quality of PUs, and the system throughput is signifieantly improved compared with other typieaspectrum sharing schemes.
