Mohamed Seif, Mohammed Karmoose, Moustafa Youssef

摘要:

审查已被提出利用在无线分布式检测网络与融合中心,以提高网络性能的错误概率方面,除了完善的节能增益。在本文中,我们进一步研究审查的基础设施少的认知无线电网络中,节点采用二进制共识算法采取全球决策的二元假设检验没有融合中心,以协调这样的过程。我们分析-并通过模拟验证-审查提高了这样的网络的性能,在错误概率和收敛时间。我们的协议显示性能增益高达46.6%的平均错误概率超过其传统的同行,除了性能增益约48.7%的平均能量消耗和节省高达50%的传输开销。

英文摘要:

Censoring has been proposed to be utilized in wireless distributed detection networks with a fusion center to enhance network performance in terms of error probability in addition to the well-established energy saving gains. In this paper, we further examine the employment of censoring in infrastructure-less cognitive radio networks, where nodes employ binary consensus algorithms to take global decisions regarding a binary hypothesis test without a fusion center to coordinate such a process. We show analytically - and verify by simulations - that censoring enhances the performance of such networks in terms of error probability and convergence times. Our protocol shows performance gains up to 46.6% in terms of average error probability over its conventional counterpart, in addition to performance gains of about 48.7% in terms of average energy expenditure and savings up to 50% in incurred transmission overhead.
