Forecasting YouTube QoE over SATCOM
2023 IEEE 97th Vehicular Technology Conference (VTC2023-Spring), 2023 We investigate the feasibility of using machine learning methods for predicting the Quality of Experience (QoE) of end users in the context of video streaming over satellite networks. To achieve this, we analyzed QoE and traffic data from 2,400 YouTube video sessions over emulated geosynchronous (GSO) satellite links.
