Choquet integral based QoS-to-QoE mapping for mobile VoD applications

Abstract

Today, how to accurately predict the quality of experience (QoE) of the networking service is a very important issue for the network operator to optimize the service. However, due to the complex multi-dimensional characteristics of QoE, QoE estimation is extremely challenging. With utilizing the advantages of quality of service (QoS) in evaluating the networking performance, we exploit QoS/QoE correlation to predict QoE by building a QoSto-QoE mapping relationship. To fully consider the inter-dependency among QoS parameters towards forming the QoE, a Choquet integral based fuzzy measurement method is used to map QoS to QoE. Via extensive experiments in mobile VoD applications, the advancement and effectiveness of the proposed method are verified.
