LPWAN技术的定义是，它们专注于扩展覆盖范围，同时保持能源效率，以牺牲数据吞吐量为代价。在这项研究中，我们能够分析LoRa，一种关键的LPWAN技术，在能源效率方面。我们对标准LoRa芯片进行了实际测量，并使用结果开发了ns-3的能耗模块。我们的贡献是对SX 1272进行的LoRa传输中不同状态的能耗分析，SX 1272是用于大多数常见LoRaWAN设备的LoRa收发器，超出了在研究中描述的三个LoRaWAN ns-3模块中使用的能耗模块，可以对基于LoRa的系统进行更准确的能耗分析。
LPWAN technologies are defined by their focus on extended coverage while maintaining energy efficiency, at the expense of data throughput. In this research we enable the analysis of LoRa, a key LPWAN technology, in terms of energy efficiency. We perform real-world measurements of a standard LoRa chip and use the results to develop an energy consumption module in ns-3. Our contributions are an analysis of the energy consumption of different states in a LoRa transmission by the SX1272, the LoRa transceiver that is used in most common LoRaWAN devices, beyond what is provided in the datasheet, and an energy consumption module for use in three of the LoRaWAN ns-3 modules described in research, enabling more accurate energy consumption analysis of LoRa-based systems.
