Michele Zorzi – QoE/QoS management in communication networks
The concepts of Quality of service (QoS) and Quality of Experience (QoE) are widely used to characterize the performance of communications, networking, and multimedia systems. According to the context, they may be obtained in various ways (analysis, simulation, experiments) based on objective (e.g., throughput or delay) or subjective (e.g., MOS, questionnaires) metrics. Recently, interdisciplinary efforts to characterize the overall performance of these systems, and the need to better understand the relationship between the user experience at the application layer and the network performance at the lower layers, are calling for a clearer definition of the QoS and QoE concepts, and for a study of their dependence on each other. This talk will try to address this issue and to discuss examples of this approach.
Michele Zorzi is a Professor at the University of Padova, an internationally recognized expert and influential researcher in the area of wireless communications and networking, and the PI for many funded research projects both in Europe and in the US. He received many awards and honors, is an IEEE Fellow, and has served three times as Editor-in-Chief of major IEEE periodicals and held several elected or appointed roles within ComSoc (including twice voting member of the BoG).
