摘要:

提出了一种适用于多主用户和多次用户的认知无线电中继网络的分布式频谱接入算法。所提出的算法背后的关键思想是PU与SU协商货币补偿的量以及SU(i)被允许的频谱接入或(ii)协作中继PU的数据的时间量,使得PU和SU的最小速率要求都得到满足。该算法被证明是灵活的优先级的主要或次要用户。我们证明了该算法将导致最好的稳定匹配,是弱帕累托最优。数值分析还表明,分布式算法可以实现的性能相比,一个最佳的集中式解决方案,但显着更少的开销和复杂性。

英文摘要:

We propose a distributed spectrum access algorithm for cognitive radio relay networks with multiple primary users (PU) and multiple secondary users (SU). The key idea behind the proposed algorithm is that the PUs negotiate with the SUs on both the amount of monetary compensation, and the amount of time the SUs are either (i) allowed spectrum access, or (ii) cooperatively relaying the PU's data, such that both the PUs' and the SUs' minimum rate requirement are satisfied. The proposed algorithm is shown to be flexible in prioritizing either the primary or the secondary users. We prove that the proposed algorithm will result in the best possible stable matching and is weak Pareto optimal. Numerical analysis also reveal that the distributed algorithm can achieve a performance comparable to an optimal centralized solution, but with significantly less overhead and complexity.
