Layer-Assisted Video Quality Adaptation for Improving QoE in Wireless Networks

IEEE Access, 2020
HTTP adaptive streaming (HAS) is a state-of-the-art technology for video streaming. Optimal adaptive streaming schemes should be designed to maximize the quality of experience (QoE) in network environments with unstable bandwidths such as wireless ...

A Queue‐Aware Extension to BBR for Low‐Latency Transport in Video Applications

IET Communications, Volume 20, Issue 1, January/December 2026.
This work addresses a long‐standing challenge in congestion control for real‐time video delivery: how to reliably maintain low latency in highly dynamic networks without sacrificing throughput. We explicitly model the excess queue incurred during bandwidth probing as a “queue debt” and then systematically “repay” this debt in subsequent phases by ...

Reliable UAV Video Streaming Over 5.9 GHz and mmWave Bands: Comparative Analysis With Fountain Codes in Urban and Industrial Environments

IET Communications, Volume 20, Issue 1, January/December 2026.
This article presents an adaptive unmanned aerial vehicle video streaming framework in which captured video is encoded at multiple quality levels and protected using Luby transform (LT) coding before transmission over a wireless channel to a base station. At the receiver, LT decoding and latency monitoring are used to assess delivery performance, while

Quality of experience enhancement through adapting sender bit rate

, 2013
With rapid growth of video traffic over Internet, it becomes a challenging task to provide perceptually good video quality. Enhancement can be done towards improving the Quality of Experience (QoE) by focusing on all relevant layers and across the ...

Versatile Video Coding Using Discrete Wavelet Transforms and Histogram Analysis

Electronics Letters, Volume 62, Issue 1, January/December 2026.
This paper proposes a novel framework that combines discrete wavelet transforms (DWT) and histogram analysis to optimise the prediction directions in VVC. Through selective reduction of prediction directions based on dominant texture orientation and minimising residual energy, the frame‐work achieves enhanced computational efficiency while maintaining ...

Predicting telemedicine system user satisfaction in sub-Saharan Africa

ICT Express, 2016
During our literature review and on-site research in developing countries, particularly in Sub-Saharan Africa, we could not point out any efforts to measure the Quality of Service (QoS) and Quality of Experience (QoE) provided by telemedicine systems ...

Adaptive Bitrate Streaming With Video Quality Enhancement

IET Image Processing, Volume 20, Issue 1, January/December 2026.
We bring the new factor, DVQE sensitivity, into the bitrate selection for the QoE improvement of adaptive video streaming. We develop DSABR, which selects chunk bitrate with high DVQE sensitivity to improve video quality as well as reduce bandwidth usage, thereby achieving efficient performance in bandwidth‐constrained network environments.
