  • Study of the Effect of the Mean and Standard Deviation of Response Time on QoE in Web Services

    Maya Tabuchi, Yoshihiro Ito

    Proceedings of ICTC 2016 ( IEEE )    637 - 639   2016.10  [Refereed]

    Research paper (international conference proceedings)   Multiple Authorship

    This paper assesses the influence of the mean and the standard deviation of the response time on Quality of Experience(QoE) for a Web service by experiments with subjects. In the experiments, the authors target actual two Web services over the Internet: map service and shopping service; they assess QoE with three scales which are based on ISO924111 usability. And then, the authors reveal the relationship the RTT and the QoE parameters by the linear regression analysis. Our experimental results show that QoE of the map service is affected by the standard deviation of the RTT more strongly than the mean of the RTT while QoE of the shopping service is influenced by the mean more than the standard deviation. Therefore, for the map service, QoS control which is reducing the packet loss by buffering and so on to maintain WebQoE. On the other hand, for the shopping service, QoS control which is reducing the delay is appropriate.

  • Study on Relationship between QoS Degradation and QoE for Web services with Personal Digital Assistant

    Research paper (international conference proceedings)   Multiple Authorship

    ThispaperstudiestheeffectoftheQoSdegradation on WebQoE with personal digital assistant (PDA) by experiment. In the experiment, the authors utilize three types of terminals: PDA, tablet PC and desktop PC; they assess QoE for two actual Web services. The experimental results show that the effect of QoS degradation on QoE with PDA is less than that of a desktop PC for one service. However, for the other service, little different between the effects is recognized. As a result, the paper confirms that the effect of QoS degradation on QoE depends on the type of a terminal.

  • Study on Novel Method of QoE Assessment with Electromyogram for an Electronic Book Webcast Service

    Kaori Iwata, Yoshihiro Ito

    Proceedings of ICTC 2016 ( IEEE )    646 - 648   2016.10  [Refereed]

    Research paper (international conference proceedings)   Multiple Authorship

    This paper studies a novel method of an electronic book Webcast service with electromyography. The proposed method has the following three features. First, we can perform the proposed method at a low cost. Second, the method does not heavily load down users. Finally, the method is portable so we can do it in many situations. This paper did experiments with 18 subjects for an actual Electronic Comics Webcast service. The experimental results show that it is effective for assessing degree of fatigue of the service to utilize the method.

  • Proposal of Method for Assessing Hierarchical Relationship between QoS and QoE for Web Services

    Yuuna Adachi, Yoshihiro Ito

    Proceedings of ICTC 2016 ( IEEE )    637 - 639   2016.10  [Refereed]

    Research paper (international conference proceedings)   Multiple Authorship

    This study proposes a novel method of evaluating hierarchical relationship between QoS and QoE for Web services by utilizing the path analysis and the principal component analysis. The proposed method shorten the number of QoS parameters each layer with the principal component analysis; it then clarify the relationship between the QoS and the QoE by performing the path analysis. To confirm the effectiveness of the proposed method, this paper does experiments with subjects for the three actual Web services and analyzes the relationship between QoS and QoE from the results by the proposed method. The experimental results show the effectiveness of this method.

  • Development of QoE Initiated Wireless LAN Base Station with DPI Based QoS Control

    Shiho Asano, Yoshihiro Ito

    Proceedings of IEICE APNOMS 2016 ( IEICE )    2016.10  [Refereed]

    Research paper (international conference proceedings)   Multiple Authorship

    In this paper, the authors develop a novel wireless LAN base station with DPI(Deep Packet Inspection) based QoS control, which can maintain QoE during congestion. In the QoS control, the base station always monitors the file type which is found in HTTP messages encapsulated in an IP packet and prioritizes the packet. Since the control is light weight, it can be easily implemented a LAN base station. The authors developed a prototype of the wireless LAN base station with WMM; and they evaluate it by QoE assessment with subjects for actual two Web services. From the experimental results, the authors show the effectiveness of the developed wireless LAN station.

  • Study on Appropriate TCP Congestion Control for WebQoE Improvement

    Masaaki Shibata,Yoshihiro Ito

    Proceedings of IEICE Workshop on Internet Architecture and Applications ( IEICE )    141 - 145   2015.11  [Refereed]

    Research paper (international conference proceedings)   Multiple Authorship

    This paper studies an appropriate TCP congestion control for a Web service from a user’s point of view by experiment. In the experiment, trying some congestion controls on both of a Web server and a Web client, the
    authors assess QoE for a Web service. This paper considers a Web shopping service as a target one and uses three major congestion controls: TCP Cubic, TCP Vegas and TCP Illinois. The experimental results show that the effect
    of the difference between the three congestion controls is not remarkable. However, in some case, when a Web client adopts TCP Vegas, the QoE for the Web service can be degraded. They confirm that the difference between congestion controls on the Web client can also affect QoE for the Web server.

  • Comparison of WebQoE between 6to4 and Teredo

    Tomohiko Mizoguchi,Yoshihiro Ito

    Proceedings of 2015 International Conference on Information and Communication Technology Convergence (ICTC)     576 - 578   2015.10  [Refereed]

    Research paper (international conference proceedings)   Multiple Authorship

    This paper compares two methods of IPv4/IPv6 coexistence from the point of view of WebQoE (Quality of Experience for Web services) by experiment. The authors adopt 6to4 and Teredo as methods of the coexistence. Almost all of the methods of the coexistence degrade QoS(Quality of Service) owing to their overheads. Consequently, they can also degrade WebQoE. However, the difference of the effect of QoS deterioration on QoE is not clarified. This paper evaluates QoS and WebQoE under both of the environment with 6to4 and that with Teredo. In the experiment, the authors utilize three actual Web services. From the experimental results, the authors confirm that both of 6to4 and Teredo degrade QoS but find the difference between effect on WebQoE with 6to4 and that of Teredo depends on Web services.
