Abstract

In Cognitive Radio Network (CRN), secondary users (SUs) opportunistically access the channel licensed by the Primary User (PU). Recently there has been growing interest in cooperative cognitive communication, spectrum leasing, and spectrum sharing techniques. These techniques have potential to substantially improve the system utilization of CRN as a whole. In this paper, we develop an elaborate and accurate queueing model for the cooperative channel access mechanisms in CRN. Using the proposed model we derive the queue length distribution of PU, as well as SU and the mean sojourn time of PU, as well as SU. We study the effect of mean arrival time of PU, mean arrival and service time of SU on the derived performance metrics. Through extensive simulation we validate the analytical model. Our analysis brings out the trade-off between the throughput of SU and transmission delay of the PU. Our results offer insight to the design engineer to optimally fix the system parameters of the CRN.

用于频谱租赁/共享的合作认知无线电网络分析框架

在认知无线电网络（CRN）中，辅助用户（SU）会择机访问主用户（PU）许可的信道。最近，人们对合作认知通信、频谱租赁和频谱共享技术的兴趣与日俱增。这些技术有可能大大提高整个 CRN 的系统利用率。在本文中，我们为 CRN 中的合作信道接入机制开发了一个详细而精确的排队模型。利用提出的模型，我们得出了 PU 和 SU 的队列长度分布，以及 PU 和 SU 的平均停留时间。我们研究了 PU 平均到达时间、SU 平均到达时间和服务时间对推导出的性能指标的影响。通过大量仿真，我们验证了分析模型。我们的分析揭示了 SU 吞吐量与 PU 传输延迟之间的权衡。我们的分析结果为设计工程师提供了洞察力，使其能够以最佳方式确定 CRN 的系统参数。
