During the planning, design, and optimization of an industrial wireless sensor network (IWSN), the proposed solutions need to be validated and evaluated. To reduce the time and expenses, highly accurate simulators can be used for these tasks. This paper presents the development and experimental validation of an ISA100.11a simulation model for industrial wireless sensor networks (IWSN). To achieve high simulation accuracy, the ISA100.11a software stack running on two types of certified devices (i.e., an all-in-one gateway and a field device) is integrated with the ns-3 simulator. The behavior of IWSNs is analyzed in four different types of test scenarios: (1) through simulation using the proposed ISA100.11a simulation model, (2) on an experimental testbed using ISA100.11a certified devices, (3) in a Gateway-in-the-loop Hardware-in-the-loop (HIL) scenario, and (4) in a Node-in-the-loop HIL scenario. Moreover, the scalability of the proposed simulation model is evaluated. Several metrics related to the timing of events and communication statistics are used to evaluate the behavior and performance of the tested IWSNs. The results analysis demonstrates the potential of the proposed model to accurately predict IWSN behavior.
在工业无线传感器网络（IWSN）的规划、设计和优化过程中，需要对提出的解决方案进行验证和评估。为了减少时间和费用，可以使用高度精确的模拟器来完成这些任务。本文提出了一种用于工业无线传感器网络（IWSN）的 ISA100.11a 仿真模型的开发和实验验证。为了实现高仿真精度，在 ns-3 模拟器上集成了运行在两种认证设备（即一体式网关和现场设备）上的 ISA100.11a 软件堆栈。在四种不同类型的测试场景中分析了 IWSN 的行为：（1）使用提出的 ISA100.11a 仿真模型进行仿真，（2）使用 ISA100.11a 认证设备在实验测试平台上进行测试，（3）在网关内回路硬件在环（HIL）场景中进行测试，以及（4）在节点内回路 HIL 场景中进行测试。此外，还评估了所提出的仿真模型的可扩展性。使用与事件定时和通信统计相关的几个指标来评估所测试的 IWSN 的行为和性能。结果分析表明，所提出的模型具有准确预测 IWSN 行为的潜力。
