无线传感器网络（WSNs）作为一种新型的工业数据采集技术，因其无需电缆的部署而受到广泛关注。然而，燃气涡轮机发动机的恶劣环境为无线传感器的部署带来了许多挑战。目前缺乏对恶劣环境对无线传感器网络影响的明确研究，这对无线传感器网络在安全关键工业仪器仪表和自动化中的部署构成了障碍。在这项研究中，作者报告的测试结果，应用无线传感器网络数据采集在燃气涡轮机发动机测试和开发一个现实的软件模拟器的目的是降低风险的无线数据传输技术在一个项目称为WIDAGATE（无线数据采集在燃气涡轮机发动机测试）。本研究提供了一个概述的仿真平台开发和调查如何小规模的测试部署在一个真实的发动机上的无线传感器网络被用来验证和改进的模拟器平台。这项工作提出了现实的物理层（无线电信道）的建模时，在恶劣的工业环境中的干扰，在航空发动机测试。基于验证，现实的物理层模型，不同的介质访问控制协议进行了模拟，以演示如何使用这种改进的模拟器可以选择一个合适的协议。
Owing to its cable-free deployment, wireless sensor networks (WSNs) have drawn great attention as a new technique for industrial data acquisition. However, the harsh environment of the gas turbine engine provides a number of challenges to deployment of wireless sensors. A definitive study of the impact of harsh environments on WSNs is currently lacking, which represents an obstacle to WSN's deployment in safety-critical industrial instrumentation and automation. In this study, the authors report the test results of applying WSNs to data acquisition in gas turbine engine testing and the development of a realistic software simulator with the purpose of de-risking the wireless data transmission technology in a project called WIDAGATE (wireless data acquisition in gas turbine engine testing). This study provides an overview of the simulation platform developed and investigates how small-scale tests of a WSN deployed on a real engine were used to validate and improve the simulator platform. This work proposes realistic modelling of the physical layer (radio channel) when subject to interference in harsh industry environment during aero-engine testing. Based on the validated, realistic physical layer model, different medium access control protocols are simulated to demonstrate how this improved simulator can be used to select an appropriate protocol.
