近年来，低功耗无线传感器执行器网络 (WSAN) 在流程工业中得到快速采用。为了满足恶劣工业环境中可靠、实时通信的关键需求，工业 WSAN 标准（例如 WirelessHART、ISA100、WIA-FA 和 6TiSCH）做出了一系列特定的设计选择，例如采用时隙信道跳频 (TSCH) 技术。这种设计选择将工业 WSAN 与传统的无线传感器网络 (WSN) 区分开来，后者是为尽力服务而设计的。最近，人们越来越有兴趣开发新方法，为运行 TSCH 和低功耗有损网络路由协议 (RPL) 的工业 WSAN 实现自主传输调度。我们的研究表明，当前的方法在分配时隙和通道时未能考虑不同设备的流量负载，这在面对高数据速率时会严重影响网络性能。在本文中，我们介绍了 ATRIA，一种用于工业 WSAN 的新型自主流量感知传输调度方法。运行 ATRIA 的设备可以根据其本地路由信息检测其流量负载，然后相应地安排其传输，而无需与相邻设备交换信息。实验结果表明，与最先进的基准相比，ATRIA 提供了显着更高的端到端网络可靠性和更低的端到端延迟，并且没有引入额外的开销。
Recent years have witnessed rapid adoption of low-power Wireless Sensor-Actuator Networks (WSANs) in process industries. To meet the critical demand for reliable and real-time communication in harsh industrial environments, the industrial WSAN standards, such as WirelessHART, ISA100, WIA-FA, and 6TiSCH, make a set of specific design choices, such as employing the Time Slotted Channel Hopping (TSCH) technique. Such design choices distinguish industrial WSANs from traditional Wireless Sensor Networks (WSNs), which were designed for best-effort services. Recently, there has been increasing interest in developing new methods to enable autonomous transmission scheduling for industrial WSANs that run TSCH and the Routing Protocol for Low-Power and Lossy Networks (RPL). Our study shows that the current approaches fail to consider the traffic loads of different devices when assigning time slots and channels, which significantly compromises network performance when facing high data rates. In this paper, we introduce ATRIA, a novel Autonomous Traffic-Aware transmission scheduling method for industrial WSANs. The device that runs ATRIA can detect its traffic load based on its local routing information and then schedule its transmissions accordingly without the need to exchange information with neighboring devices. Experimental results show that ATRIA provides significantly higher end-to-end network reliability and lower end-to-end latency without introducing additional overhead compared with a state-of-the-art baseline.
