Colloquium with Eckehard Steinbach: Quality-of-Experience driven Cross-layer Optimization for Mobile Multimedia Communication. This talk presented a Quality of Experience (QoE) based cross-layer design framework for mobile multimedia communication. Our approach leads to optimized usage of wireless network resources for multiple users running diverse applications (e.g. voice calls, video streaming, file transfer). Our main objective is to improve the user's Quality of Experience (QoE).
