Survey on QoE/QoS Correlation Models for Video Streaming over Vehicular Ad-hoc Networks

Abstract

Vehicular Ad-hoc Networks (VANETs) are a new emerging technology which has attracted enormous interest over the last few years. It enables vehicles to communicate with each other and with roadside infrastructures for many applications. One of the promising applications is multimedia services for traffic safety or infotainment. The video service requires a good quality to satisfy the end-user known as the Quality of Experience (QoE). Several models have been suggested in the literature to measure or predict this metric. In this paper, we present an overview of interesting researches, which propose QoE models for video streaming over VANETs. The limits and deficiencies of these models are identified, which shed light on the challenges and real problems to overcome in the future.

Challenges and Opportunities for Multimedia Transmission in Vehicular Ad Hoc Networks: A Comprehensive Review

“…In line with the views presented by [1,30] presents real-world measurements and analysis of video transmission over the IEEE 802.11p standard, which is specifically designed for vehicular communication. The authors conducted experiments to evaluate the performance of video streaming in terms of packet loss, delay, and video quality.…”

“…To ensure the successful transmission of this bitstream from its source to its intended destination, it is crucial to give careful consideration to various technical challenges. This involves establishing appropriate metrics, as demonstrated in Table 1, for effectively evaluating the transmission's performance [1,29].…”

“…An extensive survey, as presented by [1], investigates the correlation between Quality of Experience (QoE) and Quality of Service (QoS) models, specifically within the context of video streaming over vehicular ad hoc networks (VANETs). This work offers a comprehensive examination of these interconnected factors.…”

“…Vehicular communication is pivotal in intelligent transportation systems, aiming to provide users with advanced safety, efficiency, and infotainment services [1,2]. Within this domain, prior to the deployment of the emerging New Radio (NR), two prominent technologies dominated the vehicular network landscape, namely Dedicated Short-Range Communications (DSRCs) and Long-Term Evolution Vehicle-to-Everything (LTE-V2X) [3].…”
