基于IEEE 802.15.4的无线传感器-执行器网络（WSAN）在提高工业效率和降低运营成本方面发挥着重要作用，近年来被过程工业迅速采用。电池供电的无线模块可用于轻松、廉价地改造工业设施中的现有传感器和执行器，而无需运行通信和电源电缆。无线传感器、执行器和控制器组成一个低功耗的多跳网状网络，以交换传感数据和控制命令。如今，工业WSAN正变得比以前更大、更复杂。大型复杂的网状网络很难管理，并且一旦部署网络就无法弹性地改变。此外，基于同步的时间同步和信息分发给网络带来了显著的通信开销。更重要的是，紧急和关键信息（如紧急警报）的传递会有很长的延迟，因为这些消息必须通过逐跳传输。克服这些限制的有希望的解决方案是实现从远程无线电到IEEE 802.15.4无线电的直接消息传递。然后，可以以单跳方式将消息传递到所有现场设备。本文介绍了我们的研究，使跨技术通信（CTC）从LoRa到ZigBee（IEEE 802.15.4）使用的能量发射的LoRa无线电在2.4 GHz频段作为载体传递信息。实验结果表明，我们的CTC方法提供了可靠的通信从LoRa到ZigBee的吞吐量高达576.80 bps和误码率（BER）高达5.23%，在2.4 GHz频段。
IEEE 802.15.4-based wireless sensor-actuator networks (WSANs) have been quickly adopted by process industries in recent years because of their significant role in improving industrial efficiency and reducing operating cost. Battery-powered wireless modules can be used to easily and inexpensively retrofit existing sensors and actuators in industrial facilities without running cabling for communication and power. Wireless-enabled sensors, actuators, and controllers form a low-power multi-hop mesh network to exchange sensing data and control commands. Today, industrial WSANs are becoming tremendously larger and more complex than before. A large and complex mesh network is hard to manage and inelastic to change once the network is deployed. Besides, flooding-based time synchronization and information dissemination introduce significant communication overhead to the network. More importantly, the deliveries of urgent and critical information such as emergency alarms suffer long delay, because those messages must go through the hop-by-hop transport. A promising solution to overcome those limitations is to enable the direct messaging from a long-range radio to an IEEE 802.15.4 radio. Then messages can be delivered to all field devices in a single-hop fashion. This paper presents our study on enabling the cross-technology communication (CTC) from LoRa to ZigBee (IEEE 802.15.4) using the energy emission of the LoRa radio in the 2.4 GHz band as the carrier to deliver information. Experimental results show that our CTC approach provides reliable communication from LoRa to ZigBee with the throughput of up to 576.80bps and the bit error rate (BER) of up to 5.23% in the 2.4 GHz band.
