NB-IoT vs. LTE-M: Measurement Data of the Energy Consumption of LPWAN Technologies

NB-IoT vs. LTE-M: Measurement Data of the Energy Consumption of LPWAN Technologies This dataset contains the raw energy measurements as well as R scripts to reproduce the energy consumption plot for the corresponding paper. Each .csv file contains a specific set of measurements and we provide a script to read, process and plot the contained data. Figure 3 Mean energy consumption of the different phases for Authentication for NB-IoT and LTE-M. Due to the fact that the duration of Idle Connected in the measurement scripts was 30 seconds and 60 seconds for Idle Not Connected, the D-value and the mean power consumption are divided by 2. Data – energy_measurements_fig3.csv Code – fig3.R Figure 4 Mean energy consumption of the different phases for Data Connection and Download for NB-IoT and LTE-M for 1KB of data in HTTP. The delay between the measurements for Figure 4 were all 30 seconds long, but the identified Standby and Idle phases have different lengths. Therefore, the Idle phase values for both access technologies have been normalized and calculated for 20 seconds each. Data – energy_measurements_fig4.csv Code – fig4.R Figure 5 Mean energy consumption of the different phases for Data Connection and Download for HTTP and MQTT for 1KB of data in NB-IoT. In this scenario the delay between the measurements were different again. For MQTT the delay was 150 seconds and for HTTP 30 seconds. Therefore, the data during the Idle and Standby (only for MQTT) phase is normalized and calculated for 20 seconds and 10 seconds, respectively. During the MQTT Idle phase measurements, the device disconnects. This is not taken into account for the evaluation, which is why these energy values are discarded for this figure.

NB-IoT与LTE-M：低功耗广域网（Low Power Wide Area Network, LPWAN）技术能耗实测数据集
本数据集包含原始能耗实测数据，以及用于复现对应论文中能耗绘图的R脚本。每个.csv文件均包含一组特定的实测数据，同时配套了用于读取、处理并绘图的脚本。
图3 NB-IoT与LTE-M认证阶段各环节平均能耗。由于本次实测脚本中，空闲连接（Idle Connected）时长为30秒，非连接空闲（Idle Not Connected）时长为60秒，因此D值与平均功耗需除以2。

代码文件：fig3.R
图4 针对HTTP协议下1KB数据传输，NB-IoT与LTE-M的数据连接与下载阶段各环节平均能耗。本次图4的实测间隔时长均为30秒，但识别出的待机（Standby）与空闲（Idle）阶段时长存在差异。因此已对两种接入技术的空闲阶段数值进行归一化处理，统一按20秒计算。

图5 针对NB-IoT网络下1KB数据传输，HTTP与MQTT协议的数据连接与下载阶段各环节平均能耗。本次场景的实测间隔时长再次存在差异：MQTT协议的间隔为150秒，HTTP协议为30秒。因此需分别对空闲与待机（仅MQTT协议）阶段的数据进行归一化处理，分别按20秒与10秒计算。在MQTT空闲阶段的实测过程中，设备会断开连接，该情况未纳入评估范围，因此该阶段的能耗数值已从本图中剔除。
