论文摘要

物联网应用程序(IoT)应用程序的远程和低能消耗要求导致了一种新的无线通信技术,称为低功率广泛区域网络(LPWANS)。近年来,作为LPWAN最有前途的技术之一,远距离(LORA)方案引起了很多关注。在洛拉网络中,选择正确的传输参数组合是一个主要挑战。在洛拉(Lora)中,执行自适应数据速率(ADR)机制来配置每个端设备的(ED)传输参数,从而改善了性能指标。在本文中,我们提出了一种基于链接的ADR方法,该方法旨在通过做出决定而无需考虑最后一个接收的数据包的历史,从而配置ED的传输参数,从而导致相对较低的空间复杂性方法。在这项研究中,我们介绍了评估性能的四种不同方案,包括考虑移动ED的场景。我们的仿真结果表明,在具有高通道噪声的移动方案中,我们提出的算法的数据包输送率(PDR)的表现要优于原始ADR的2.8倍,而其他相关算法的1.35倍。

The long-range and low energy consumption requirements in Internet of Things (IoT) applications have led to a new wireless communication technology known as Low Power Wide Area Network (LPWANs). In recent years, the Long Range (LoRa) protocol has gained a lot of attention as one of the most promising technologies in LPWAN. Choosing the right combination of transmission parameters is a major challenge in the LoRa networks. In LoRa, an Adaptive Data Rate (ADR) mechanism is executed to configure each End Device's (ED) transmission parameters, resulting in improved performance metrics. In this paper, we propose a link-based ADR approach that aims to configure the transmission parameters of EDs by making a decision without taking into account the history of the last received packets, resulting in a relatively low space complexity approach. In this study, we present four different scenarios for assessing performance, including a scenario where mobile EDs are considered. Our simulation results show that in a mobile scenario with high channel noise, our proposed algorithm's Packet Delivery Ratio (PDR) is 2.8 times outperforming the original ADR and 1.35 times that of other relevant algorithms.
