摘要

LoRaWAN 已成为 LPWAN 的旗舰技术，也是物联网设备的主要连接选择之一。由于 LoRaWAN 专为低能耗而设计，因此了解其能耗性能至关重要。本文研究了数据包大小对 LoRaWAN 设备每交付数据位（EPB）能耗的影响。通过大量仿真，我们发现，当网络性能非常高或非常低时，EPB 会随数据包大小的变化而稳步降低；反之，EPB 可能会随数据包大小的变化而呈现 "非对称 U "型，在中等数据包大小时会达到最小 EPB 值。我们还详细分析了产生这些观察到的行为的原因。

Understanding the impact of packet size on the energy efficiency of LoRaWAN

LoRaWAN has become a flagship LPWAN technology, and one of the main connectivity alternatives for IoT devices. Since LoRaWAN was designed for low energy consumption, it is fundamental to understand its energy performance. In this paper, we study the impact of packet size on LoRaWAN device energy consumption per delivered data bit (EPB). By means of extensive simulations, we show that, when network performance is very high or very low, EPB decreases steadily with packet size; otherwise, EPB may show an “asymmetric U” shape as a function of packet size, with a minimum EPB value that is achieved for a medium packet size. We also provide detailed insights on the reasons that produce the observed behaviors.
