Abstract

LoRaWAN, a low-power wide-area network (LPWAN) technology, has been successfully used in the Internet of Things (IoT) industry over the last decade. It is an easy-to-use, long-distance communication protocol combined with minimal power consumption. Supporting critical downlink traffic in LoRaWAN networks is crucial for ensuring the reliable and efficient delivery of essential data in certain actuating applications. However, challenges arise when prioritizing critical downlink traffic, including commands, alerts, and emergency notifications that demand immediate attention from actuating devices. This paper explores strategies to improve downlink traffic delivery in LoRaWAN networks, focusing on enhancing reliability, fairness, and energy efficiency through prioritization techniques and network parameter configurations in the EU868 spectrum. Theoretical as well as simulation results provide insights into the effectiveness of the available solutions for supporting critical downlink traffic in LoRaWAN networks.

支持 LoRaWAN 中的关键下行链路流量

LoRaWAN 是一种低功耗广域网（LPWAN）技术，在过去十年中已成功应用于物联网（IoT）行业。它是一种易于使用的长距离通信协议，功耗极低。在某些执行应用中，支持 LoRaWAN 网络中的关键下行链路流量对于确保可靠、高效地传输重要数据至关重要。然而，在确定关键下行链路流量（包括需要执行设备立即关注的命令、警报和紧急通知）的优先级时，会出现一些挑战。本文探讨了改善 LoRaWAN 网络下行链路流量传输的策略，重点是通过 EU868 频谱中的优先级技术和网络参数配置来提高可靠性、公平性和能效。理论和仿真结果有助于深入了解现有解决方案在 LoRaWAN 网络中支持关键下行链路流量的有效性。

期刊介绍： Computer and Communications networks are key infrastructures of the information society with high socio-economic value as they contribute to the correct operations of many critical services (from healthcare to finance and transportation). Internet is the core of today''s computer-communication infrastructures. This has transformed the Internet, from a robust network for data transfer between computers, to a global, content-rich, communication and information system where contents are increasingly generated by the users, and distributed according to human social relations. Next-generation network technologies, architectures and protocols are therefore required to overcome the limitations of the legacy Internet and add new capabilities and services. The future Internet should be ubiquitous, secure, resilient, and closer to human communication paradigms. Computer Communications is a peer-reviewed international journal that publishes high-quality scientific articles (both theory and practice) and survey papers covering all aspects of future computer communication networks (on all layers, except the physical layer), with a special attention to the evolution of the Internet architecture, protocols, services, and applications.
