分布式传感器网络中的鲁棒顺序检测

Robust Sequential Detection in Distributed Sensor Networks

Mark R. Leonard, Abdelhak M. Zoubir

摘要:

我们考虑非高斯噪声环境下分布式传感器网络的顺序二元假设检验问题。为此,我们提出了共识+创新序贯概率比检验(CISPRT)的一般公式。此外,我们引入了两个不同的概念,鲁棒的CISPRT,并提出了四种不同的算法,即,最有利的密度CISPRT,中位数CISPRT,M-CISPRT,和Myriad-CISPRT。随后,我们分析了它们对不同二元假设检验的适用性,然后验证和评估它们在均值偏移和方差偏移场景中的性能。

英文摘要:

We consider the problem of sequential binary hypothesis testing with a distributed sensor network in a non-Gaussian noise environment. To this end, we present a general formulation of the Consensus + Innovations Sequential Probability Ratio Test (CISPRT). Furthermore, we introduce two different concepts for robustifying the CISPRT and propose four different algorithms, namely, the Least-Favorable-Density-CISPRT, the Median-CISPRT, the M-CISPRT, and the Myriad-CISPRT. Subsequently, we analyze their suitability for different binary hypothesis tests before verifying and evaluating their performance in a shift-in-mean and a shift-in-variance scenario.
