基于IEEE 802.15.4的无线传感器-执行器网络在提高工业效率和降低运营成本方面具有重要作用，近年来被过程工业广泛采用。今天，工业无线传感器-执行器网络正变得比以前更大、更复杂。然而，一个大型的、复杂的网状网络很难管理，并且一旦网络部署就没有弹性。此外，基于洪水的时间同步和信息分发给网络带来了巨大的通信开销。更重要的是，紧急和关键信息（如紧急警报）的传递遭受了长时间的延迟，因为这些信息必须通过逐跳传输。克服这些限制的一个有希望的解决方案是启用从远程无线电到IEEE 802.15.4无线电的直接消息传递。然后，消息可以以单跳方式传递到所有现场设备。本文介绍了利用LoRa无线电的能量发射作为信息传递载体，实现LoRa向ZigBee跨技术通信的研究。实验结果表明，本文提出的跨技术通信方法在2.4 GHz频段提供了从LoRa到ZigBee的可靠通信，吞吐量高达576.80 bps，误码率高达5.23%。
IEEE 802.15.4-based wireless sensor-actuator networks have been widely adopted by process industries in recent years because of their significant role in improving industrial efficiency and reducing operating costs. Today, industrial wireless sensor-actuator networks are becoming tremendously larger and more complex than before. However, a large, complex mesh network is hard to manage and inelastic to change once the network is deployed. In addition, 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 delays, 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 article presents our study on enabling the cross-technology communication from LoRa to ZigBee using the energy emission of the LoRa radio as the carrier to deliver information. Experimental results show that our cross-technology communication approach provides reliable communication from LoRa to ZigBee with the throughput of up to 576.80 bps and the bit error rate of up to 5.23% in the 2.4 GHz band.
