QoE-Based Analysis of DASH Streaming Parameters Over Mobile Broadcast Networks

IEEE Access, 2017
Multimedia services over mobile networks are subject to multiple factors that affect the quality of experience (QoE) perceived by users. In a long term evolution (LTE) multimedia broadcast service, these factors are initial delay, technical quality of ...

Long-Term Video QoE Assessment Studies: A Systematic Review

IEEE Access, 2022
Although longitudinal studies are common in other disciplines, such as psychology, medicine, or User Experience, they are rarely used in Quality of Experience (QoE). However, observing users over time can provide useful information on the QoE and help to

Framework for Task Offloading in O‐RAN Architecture for Heterogeneous Computing Applications

Transactions on Emerging Telecommunications Technologies, Volume 37, Issue 2, February 2026.
This work proposes a task offloading framework in ORAN architecture, optimizing computational assignment across user devices, edge cloud, and regional cloud. By efficiently selecting processing nodes and allocating computational and radio resources, it minimizes delay while accommodating diverse latency requirements for gold, silver, and bronze‐tier ...

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 ...

Why is Multimedia Quality of Experience Assessment a Challenging Problem?

IEEE Access, 2019
Quality of experience (QoE) assessment occupies a key role in various multimedia networks and applications. Recently, large efforts have been devoted to devise objective QoE metrics that correlate with perceived subjective measurements.

Towards DRL‐Based Resource Allocation for Delay‐Aware Video Delivery in Cloud‐Edge‐Device Networks

IET Communications, Volume 20, Issue 1, January/December 2026.
This paper proposes a delay‐aware cloud‐edge‐device collaborative video delivery strategy, designing a three‐tier architecture and a fine‐grained scheduling model to enable dynamic caching and adaptive transcoding. An actor–critic deep reinforcement learning agent is introduced to jointly optimize caching, computing and radio resource allocation ...

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

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 ...

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 ...
