认知无线电中考虑机会容量的多业务资源分配
Resource allocation based on opportunistic capacity for cognitive radio networks with heterogeneous services
摘要
Abstract
The spectrum resource is time-varied in cognitive radio networks (CRNs) with dynamic spectrum environment,which makes the traditional static chunk-based allocation be of poor performance. To solve this issue,this paper derives an opportunistic capacity model for chunks with time-varied spectrum resources and presents an opportunistic capacity based chunk allocation model for heterogeneous services for CRNs under the time-varied spectrum environment.Simulation results illustrate that the proposed scheme can guarantee the Quality of Service (QoS) requirements of heterogeneous services in the situation with time-varied spectrum resources.关键词
