QoE-based management of medical video transmission in wireless networks

The prevalence of broadband wireless networks offering nearly ubiquitous Internet connectivity today has opened new possibilities for utilizing wireless and mobile services also in eHealth applications. However, such services often involve transmission of critical multimedia data, thus having stringent requirements for network Quality of Service (QoS) not supported in current networks. In this paper, we propose means for implementing enhanced QoS support for medical video transmission in wireless networks. Our solution extends existing wireless network QoS architectures with support for differentiating multiple flows and packets of the same service type based on their impact on the Quality of Experience (QoE). The paper also presents an experimental evaluation of the solution in a simulation environment. The simulation results indicate that our solution enhances the QoE significantly and therefore improves the availability of critical medical video services.
