Datasets

This folders contain the datasets for the paper "Evaluation of O-RAN 5G and 6G Networks: Experimental Design and Data". All the datasets are in CSV format and can be easily loaded using pandas. The datasets are organized in three folders corresponding to three different network settings.

1. Folder computing_datasets

It contains the datasets with the computing utilization per core. The folder has two subfolders
named datasets_unpin and datasets_pin with all the measurements for the cases of unpinned gNBs and pinned gNBs. * Datasets inside the folder datasets_unpin measure the commputing utilization per core when deploying a number of vBSs that can use all the CPUs available. * Datasets inside the folder datasets_unpin measure the commputing utilization per core when deploying a number of vBSs with specific pinning configurations

2. Folder energy_datasets

It contains two the energy measurement datasets. The file dataset_ul.csv provides a set of measurement of performance and power consumption of a virtualized Base Station when using only the uplink chanel. On the other hand, the file dataset_dlul.csv provides a set of measurement of performance and power consumption when using both the downlink and uplink channel.
