基于IEEE 802.15.4的工业无线网络已被广泛部署用于连接工业设施中的传感器、执行器和网关。尽管由于多年的研究，无线Mesh网络在大多数情况下都能令人满意地工作，但一旦部署网络，它们往往很复杂，很难管理。此外，由于所有消息都必须通过逐跳传输，因此时间关键型消息的传递会受到很长时间的延迟。最近的研究表明，为网络中的每个设备添加一个低功率广域网(LPWAN)无线电可以有效地克服这种限制，因为网络管理和时间关键的消息可以通过远距离LPWAN链路直接从网关传输到现场设备。然而，行业从业者明显不愿接受新的解决方案，因为硬件改装的成本很高。本文提出了一种新的系统，即直接消息传播(DIME)系统，它利用跨技术通信技术，在工业无线网络中实现从网关到现场设备的直接消息传播，而不需要为每个现场设备增加第二个无线电。实验结果表明，与最先进的基准相比，我们的系统有效地减少了时间关键型消息的传递延迟，并提高了网络可靠性。
IEEE 802.15.4 based industrial wireless networks have been widely deployed to connect sensors, actuators, and gateway in industrial facilities. Although wireless mesh networks work satisfactorily most of the time thanks to years of research, they are often complex and difficult to manage once the networks are deployed. Moreover, the deliveries of time-critical messages suffer long delay, because all messages have to go through hop-by-hop transport. Recent studies show that adding a low-power wide-area network (LPWAN) radio to each device in the network can effectively overcome such limitations, because network management and time-critical messages can be transmitted from gateway to field devices directly through long-distance LPWAN links. However, industry practitioners have shown a marked reluctance to embrace the new solution because of the high cost of hardware modification. This paper presents a novel system, namely DIrect MEssage dissemination (DIME) system, that leverages the cross-technology communication technique to enable the direct message dissemination from gateway to field devices in industrial wireless networks without the need to add a second radio to each field device. Experimental results show that our system effectively reduces the latency of delivering time-critical messages and improves network reliability compared to a state-of-the-art baseline.
