the RPL metrics can be assumed as QoS parameters of RPL. For more information, see the following sources:

Anatol Badach Sir, the articles you quoted are helpful. But I have shortlisted the QoS parameters (in terms of RPL metrics) I want to explore the secondary/existing datasets to justify my readings and further optimisations in RPL. Hence, I am particularly looking for datasets in mobile RPL and IoV. If you can assist me with those, it will be really helpful.
the QoS parameters in the IoV are mainly relevant for the communication types "Vehicle-to-Infrastructure", "Vehicle-to-Network" and "Vehicle-to-Vehicle". For the communication types "Vehicle-to-Pedestrian" and Vehicle-to-Vehicle ", however, the QoE parameters are of great importance. See these sources.
Best regards
