摘要

本文研究了各种工业应用中无线传感器网络(WSN)同步的关键问题。本文分析了低成本传感器网络拓扑结构。本文对低成本传感器网络拓扑结构进行了分析,在不同条件下进行了通信延迟测量和定量抖动分析,并介绍了不同硬件实现的 WSN 的传播时间延迟与数据比特率和调制类型的关系。通过实验概率密度函数评估了时间延迟分布对 WSN 各层时间同步误差传播的影响。提出了基于可控传播延迟抖动方法的网络同步。这项研究从定量角度揭示了 WSN 同步的复杂性,为优化网络配置和参数以延长低功耗传感器节点的工作寿命奠定了基础。

Time Delay Characterization in Wireless Sensor Networks for Distributed Measurement Applications
This paper investigates the critical aspect of synchronization in wireless sensor networks (WSNs) across diverse industrial applications. The low-cost sensor network topologies are analyzed. The communication delay measurements and quantitative jitter analysis are performed under different conditions, and dependencies of the propagation time delay on the data bitrate and modulation type for different hardware implementations of the WSNs are presented. The time delay distribution influence on the time synchronization error propagation over WSN layers was assessed from the experimental probability density functions. The network synchronization based on the controlled propagation delay jitter approach has been proposed. This research contributes quantitative insights into the complexities of synchronization in WSNs, offering a foundation for optimizing network configurations and parameters to extend the operational life of low-power sensor nodes.

期刊介绍: Journal of Sensor and Actuator Networks (ISSN 2224-2708) is an international open access journal on the science and technology of sensor and actuator networks. It publishes regular research papers, reviews (including comprehensive reviews on complete sensor and actuator networks), and short communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced.
