Streaming Video QoE Modeling and Prediction: A Long Short-Term Memory Approach
Nagabhushan Eswara,S. Ashique,Anand Panchbhai,Soumen Chakraborty,Hemanth P. Sethuram,Kiran Kuchi,Abhinav Kumar,Sumohana S. Channappayya +7 more
TL;DR: In this article, a recurrent neural network-based QoE prediction model using an LSTM network is proposed, which is a network of cascaded long short-term memory (LSTM) blocks to capture the nonlinearities and the complex temporal dependencies involved in the time-varying QoEs.

A Continuous QoE Evaluation Framework for Video Streaming Over HTTP
Nagabhushan Eswara,K. Manasa,Avinash Kommineni,Soumen Chakraborty,Hemanth P. Sethuram,Kiran Kuchi,Abhinav Kumar,Sumohana S. Channappayya +7 more
TL;DR: This paper presents a database consisting of videos at full high definition and ultrahigh definition resolutions, and presents a QoE evaluation framework comprising a learning-based model during playback and an exponential model during rebuffering, and performs an objective evaluation of popular video quality assessment and continuous timeQoE metrics over the constructed database.
Journal ArticleDOI
Adaptive User Pairing for NOMA Systems With Imperfect SIC
TL;DR: The proposed adaptive user pairing (A-UP) algorithm results in better performance than state-of-the-art NOMA pairing algorithms in the presence of SIC imperfections and is proposed for achieving better user rates.
Journal ArticleDOI
Energy and Throughput Trade-Offs in Cellular Networks Using Base Station Switching
TL;DR: A set of BSS patterns, at a global system-level, that have the potential to provide full coverage if the appropriate schedulers are used and can be used to quantify, offline, the energy-performance trade-offs under different operating scenarios.
Proceedings ArticleDOI
Performance Evaluation of LAA-LBT Based LTE and WLAN's Co-Existence in Unlicensed Spectrum
TL;DR: Through simulation results, it is shown that there exists a trade off in selection of the detection threshold such that high sensing threshold results in improved overall network throughput at the cost of WLAN's performance; whereas, low thresholdresults in improved W LAN's performance at thecost of the overall network performance.
