A Spectrum Sharing Algorithm for Non-real-time Service in Cognitive Radio Networks
Zhao Xiao-chuan · Radio Engineering of China · 2010
In order to improve the spectrum efficiency and average profile of the users,cognitive radio network needs a special spectrum sharing scheme when the users in the network have a special kind of service with a special QoS.In this paper,the spectrum sharing scheme in the scenario of the users having non-real-time service in the cognitive radio network is researched.A spectrum sharing algorithm is proposed for non-real-time service,according to the service quantity and the spectrum quality,named NRT-dedicate spectrum sharing algorithm.The simulation showed that the proposal algorithm is more efficiency than common spectrum sharing algorithm for non-real-time service.
