Quality of Experience in Mobile Cloud Computing
Research Guide
What is Quality of Experience in Mobile Cloud Computing?
Quality of Experience (QoE) in Mobile Cloud Computing evaluates user-perceived performance in mobile thin-client systems accessing cloud-rendered content like games and media.
Researchers measure QoE through subjective scores correlated with objective metrics such as latency, video quality, and interactivity in cloud gaming and remote desktop scenarios. Over 10 key papers from 2012-2022, with 153 citations for Wen et al. (2014), address QoE in mobile cloud media and gaming. Studies focus on thin-client streaming over wireless networks.
Why It Matters
QoE models guide optimizations in cloud gaming services like Stadia and GeForce Now, enabling thin clients to deliver high-fidelity experiences over mobile networks (Di Domenico et al., 2021; 66 citations). In mobile virtualization, QoE metrics drive resource provisioning to minimize delay and cost while maximizing user satisfaction (Basiri and Rasoolzadegan, 2016; 35 citations). These insights support scalable Desktop-as-a-Service deployments, reducing hardware needs for end-users (Magaña et al., 2019; 26 citations).
Key Research Challenges
Network Latency Impact
Variable mobile network delays degrade interactivity and video smoothness in cloud gaming. Peñaherrera-Pulla et al. (2021; 49 citations) measure key indicators over wireless links, showing latency thresholds for acceptable QoE. Mitigating jitter remains difficult in real deployments.
Subjective-Objective Correlation
Mapping user ratings to network parameters requires robust models amid diverse devices. Slivar et al. (2014; 29 citations) conduct empirical studies on in-home streaming, revealing gaps in prediction accuracy. Factors like content type complicate generalization.
Resource Provisioning Efficiency
Balancing CPU/GPU virtualization with QoE demands dynamic allocation. Basiri and Rasoolzadegan (2016; 35 citations) propose delay-aware methods for cost efficiency. Scaling to global users challenges real-time adaptation.
