Abstract

The paper (Stefanski and Sadowski, EURASIP J. Wirel. Commun. Netw. 2018, Article 179) introduces a multilateration algorithm for unsynchronized sensor networks. However, a very similar method has been proposed before that is not cited. Furthermore, in the measurement model of Stefanski and Sadowski (EURASIP J. Wirel. Commun. Netw. 2018, Article 179), an incorrect covariance matrix (Eq. (11) in Stefanski and Sadowski (EURASIP J. Wirel. Commun. Netw. 2018, Article 179)) has been used that leads to inferior results. We summarize the context and explain the measurement methodology proposed in Stefanski and Sadowski (EURASIP J. Wirel. Commun. Netw. 2018, Article 179), while referring to the missing citation. Finally, we derive the correct covariance matrix of the measurement error and demonstrate that the covariance matrix proposed in Stefanski and Sadowski (EURASIP J. Wirel. Commun. Netw. 2018, Article 179) is incorrect.

摘要

该论文（Stefanski和Sadowski，EURASIP J.Wirel.Commun.Netw.2018，第179条）介绍了一种用于非同步传感器网络的多边定位算法。然而，在此之前未提出非常相似的方法。此外，在Stefanski和Sadowski的测量模型（EURASIP J.Wirel.Commun.Netw.2018，第179条）中，Stefanski和Sadowski的错误协方差矩阵（方程（11））（EURASIP J.Wirel.Commun.Netw。 2018年，第179）条已被使用，导致结果较差。我们总结了上下文并解释了Stefanski和Sadowski提出的度量方法（EURASIP J.Wirel.Commun.Netw.2018，第179条），同时提到了缺少的引文。最后，
