QoS and QoE modelling in video stream service over wireless and mobile network

Abstract

Customer satisfaction is essential in every service. In video stream service over wireless and mobile network, customer satisfaction is determined by objective Quality of Service (QoS) that derived from network, application and mobile device parameters. Some of these parameters can be adjusted i.e. video resolution, audio rate, and bandwidth while the others are not fully controllable i.e. network throughput, delay, and packet lost probability. However, the customer satisfaction in this service is not only determined by QoS. There is subjective Quality of user Experience (QoE). It defines customer perceived quality over the service. It is influence by intrinsic factors (customer experience, customer expectation, and customer interest) and extrinsic factors (saliency awareness, frame loss distribution, and frame loss to frame rate awareness). This journal will discuss a holistic view of the quality of video stream service over wireless and mobile network in order to elaborate intermingled interrelation of QoS parameters, nonlinearity of QoE factors and their contribution to enhance customer satisfaction. The contribution of this journal is to propose a methodology in developing schemes that model the QoS and QoE.
