An Improved Centralized Cognitive Radio Network Spectrum Allocation Algorithm Based on the Allocation Sequence
2013
International Journal of Distributed Sensor Networks
The demand of the wireless communications service is increasing in recent years, and the demand of the wireless communication rate is increasing too. However, the static spectrum allocation mechanism results in lots of free spectrum resources in space, and the spectrum is wasted. The cognitive radio technology with intelligent searching and efficient utilization of the idle spectrum resources just provides the opportunity to use the free spectrum resources. Thus, the spectrum allocation
