“…In order to create models, the proposed mathematical models for audiovisual - QoE model associated with MOBA game can be simply created using the concept of the Simple Additive Weighting (SAW) that is presented as follows [ 29 ]: Where MOS SAW is the overall MOS based on SAW, while w j and MOS j are is the weight and the MOS of criteria j respectively. Furthermore, this proposed model also followed (10) in Table 2 , which is the QoE model for video telephony [ 35 ]. Nevertheless, there is advancement beyond [ 35 ], since the gathered data of audiovisual quality have been also applied to the QoE model.…”

“…They studied with various scenarios before performing the analysis, and then proposed several mathematical models, including two models for the short conversation test as in (8) and the audiovisual short conversation test as shown in (8)–(9) respectively. Lastly, Pornpongtechavanicha and Daengsi [ 35 ] conducted the study based on video telephony. This work was conducted with about 200 subjects who participated the subjective tests with short conversation scenario via two applications, LINE and Skype.…”

With the advancement of multimedia communications and information technologies, online video games have become very popular recreational activities worldwide, while Multiplayer Online Battle Arena (MOBA) games have gained immense popularity from game players in recent times. Therefore, based on quality of experience, audiovisual quality evaluation models for MOBA games have been proposed in this study. The subjective data from 210 game players (both males and females) about audio quality during conversation, the video quality, the overall quality, and the weighted percentage of video and voice have been collected from small competition events of the Garena ROV (Arena of Valor) in Hua Hin, Thailand. The data from 160 game players have been used to create the models, while the data from 50 game players have been applied for model performance evaluation. After developing the models, Mean Absolute Percentage Error (MAPE) technique has been utilized for model evaluation. On completion of this study, it was found that two thirds of the proposed models provide better performance than the other previous works. All of them, called MOS Audiovisual-MOBA1 model, MOS Audiovisual-MOBA2 model and MOS Audiovisual-MOBA3 model, show excellent performances with MAPE values of 4.95%, 5.92% and 4.75% respectively. Therefore, excellent performance of these proposed models becomes one of the contributions of this study. Also, this evidence of excellent model performance makes the proposed models ideal for utilization for assessment of audiovisual quality of the MOBA games. All audiovisual quality evaluation models provide excellent efficiencies.

“…The existing QoS/QoE models analyse the parameters of the network separately [16]. However, this approach does not take into account the correlation between the network parameters, what implies that small errors in the measurements of one parameter may lead to considerable variations of the estimated parameters and, as a result, the constructed model will be instable.…”

This paper analyzes the quality of Virtual Reality (VR) / Augmented Reality (AR) video streamed in harsh industrial environments. VR/AR is being used in the Industrial Internet of Things (IIoT) as one of the most promising applications for favouring labour conditions and increasing security, while reducing costs of manufacturing. We provide an empirical work that analyzes the impact of industrial environment within the assessment of the video quality transmitted over WiFi and 5G C-band access and discuss the impact of electromagnetic emission of industrial machines in radiocommunications (microwave bands). Even if the presented measurements are limited, they clearly show some aspects of the impact of industrial environments that should be taken into account when developing multimedia IIoT applications. Moreover, we discuss the differences between Radiocommunications technologies for building separated (private) Small Area Wireless Networks (SAWN) for the IIoT in factories.
