prr_coexistence.csv contains data used to generate the figure in Section 5.5.

The columns are described in the following list:

• prr_baseline: PRR of the baseline case (DSME-LoRa nodes without cross-traffic)
• prr_cross: PRR of the LoRaWAN cross-traffic case

interference_prr_moving_avg.csv contains data used to generate the moving average PRR under interference from jammers in Section 5.6

The columns are described in the following list:

• t_r<x>: Time axis of the replica x
• prr_r<x>: Prr axis of the replica x

energy.csv contains raw current measurements used for Section 5.7

The columns are described in the following list:

• n: The sample index
• cap: Current samples for CAP transmission
• cfp: Current samples for CFP transmission
• cfp_rx: Current samples for CFP transmission (RX node)

simulation.csv contains all simulation data used for the experiments (Sections 6,7). This file is the output of Omnet++ Scavetool for all simulation results. See (Result Analysis with Python)[https://docs.omnetpp.org/tutorials/pandas/] from the official Omnet++ documentation for performing data analysis on this data.

Generate data sources from raw logs

data_transmission.csv, prr_coexistence.csv and interference_prr_moving_avg.csv are generated from raw log files. To generate these files from the original raw data, extract raw_logs.tar.gz (pass:tosn_dsme_lora_2022) in this folder and execute get_all.sh
