This paper introduces a novel approximation of the widely used full reference SSIM metric, ideal for the in-network assessment of QoE for multimedia streams. The QoE estimation approximation algorithm has been implemented as a Virtualised Network Function (VNF) in order to be deployed over Network Function Virtualisation (NFV) infrastructures. The proposed method is based on a two steps evaluation...
The increasing popularity of video (i.e., audio-visual) applications or services over both wired and wireless links has prompted recent growing interests in the investigations of quality of experience (QoE) in online video transmission. Conventional video quality metrics, such as peak-signal-to-noise-ratio and quality of service, only focus on the reception quality from the systematic perspective...
The dynamic and shared nature of wireless medium imposes an adverse barrier to supporting QoS for video streaming applications in wireless networks. In this paper, we investigate a case study of video streaming in a wireless mesh network to obtain important observations on the factors which impact video quality in multihop wireless mesh networks. Based on our analysis of the case study, we propose...
