认知无线电网络中的分布式上行资源分配--第一部分:功率分配均衡与算法

Distributed Uplink Resource Allocation in Cognitive Radio Networks -- Part I: Equilibria and Algorithms for Power Allocation

Mingyi Hong, Alfredo Garcia, Stephen Wilson

摘要:

频谱管理已被确定为实现认知无线电网络(CRN)技术的关键一步。当前处理CRN中的频谱管理的大多数工作集中于问题的单个任务,例如,频谱感测、频谱决策、频谱共享或频谱移动性。在这篇由两部分组成的论文中,我们认为,对于某些网络配置,联合执行几个任务的频谱管理提高了频谱效率。具体来说,我们的目标是研究在CRN的上行链路资源管理问题,存在多个认知用户(CU)和接入点(AP)。为了最大化其上行链路传输速率,CU必须与合适的AP相关联(频谱决策),并且与其他CU共享由该AP使用的信道(频谱共享)。这些任务显然是相互依存的,如何有效地以分布式方式执行这些任务的问题在文献中仍然是开放的。

英文摘要:

Spectrum management has been identified as a crucial step towards enabling the technology of a cognitive radio network (CRN). Most of the current works dealing with spectrum management in the CRN focus on a single task of the problem, e.g., spectrum sensing, spectrum decision, spectrum sharing or spectrum mobility. In this two-part paper, we argue that for certain network configurations, jointly performing several tasks of the spectrum management improves the spectrum efficiency. Specifically, our aim is to study the uplink resource management problem in a CRN where there exist multiple cognitive users (CUs) and access points (APs). The CUs, in order to maximize their uplink transmission rates, have to associate to a suitable AP (spectrum decision), and to share the channels used by this AP with other CUs (spectrum sharing). These tasks are clearly interdependent, and the problem of how they should be carried out efficiently and in a distributed manner is still open in the literature.
