Approaches for Utility-Based QoE-Driven Optimization of Network Resource Allocation for Multimedia Services

Taking jointly into account end-user QoE and network resource allocation optimization provides new opportunities for network and service providers in improving user perceived service performance. In this chapter, we discuss state-of-the-art with regards to QoE-driven utility-based optimization of network resource allocation, in particular related to multimedia services. We present two general types of approaches: those which are primarily user-centric and those which are primarily network-centric. Finally, we provide a comparison of the analyzed approaches and present open issues for future research.
