A study on QoS/QoE correlation model in wireless-network

With the rapid development of wireless network technologies and multimedia communications, video services play an increasingly important role in network communications. Most traditional quality assessment methods of video services are designed based on QoS (Quality of Service, QoS) evaluation parameters. Subject test represents the most reliable quality evaluation method and QoE (Quality of Experience) is usually to be used to represent the subjective evaluation for network communications. Compared with QoE from the subjective test, QoS parameters are much easier to be obtained. In this paper, we use a QoS/QoE mapping assessment model for the relationship between QoS and QoE and test it by the experiments in NS2 network simulation environment. Experimental results demonstrate that the QoE can be obtained by QoS parameters in network communications.
