Study on a Method of Estimations QoS for In-Vehicle Network with SPQ of IEEE802.1 Reviewed International journal
Chisa Kobayashi, Yoshihiro Ito
Proceedings of 2020 IEEE 8th Global Conference on Consumer Electronics (GCCE) 2020.10
Language：English Publishing type：Research paper (international conference proceedings) Publisher：IEEE
This paper studies a method of estimation QoS for
in-vehicle Ethernet with SPQ. Although SPQ is the simplest and
the most fundamental control, the estimation method of QoS is not yet clear for an in-vehicle Ethernet with multiple switches. The authors evaluate QoS provided by SPQ by simulation. By adapting the regression analysis to the results, the authors obtain an equation of estimating QoS and show its effectiveness. -

Study on EDCA Parameter Tuning over Congested Wireless LAN Based on WebQoE Reviewed
Kosuke Niwa, Yoshihiro Ito
J103-B ( 1 ) 22 - 28 2020.01
Language：Japanese Publishing type：Research paper (scientific journal) Publisher：The Institute of Electronics, Information and Communication Engineers
This paper studies appropriate values of EDCA parameters for the authors' developed wire- less LAN station, which can reduce the bandwidth usage without deteriorating QoE (Quality of Experience) for a Web service. As a QoS control, the wireless LAN station utilizes EDCA, which is standardized in IEEE 802.11e; EDCA has some parameters for QoS control. However appropriate values of the EDCA parameters for the station have never been discussed. The authors study values of EDCA parameters which can reduce more bandwidth usage without degrading QoE by using QoS-QoE mapping equations. Moreover they assess QoE for actual two Web services by an experiment with subjects and confirm that the obtained parameters are effective.

Proposal of Multi-path TCP Packet Scheduler to Adjust Trade-off between QoS Fluctuation and Throughput for WebQoE Improvement Reviewed International journal
Kensuke Noda, Yoshihiro Ito
Proceedings of 2019 IEEE 4th International Conference on Computer and Communication Systems (ICCCS) 493 - 496 2019.02
Language：English Publishing type：Research paper (international conference proceedings) Publisher：IEEE
This paper proposes a new MPTCP packet scheduler for improvement of Quality of Experience for a Web service (WebQoE); it suppresses the Quality of Service (QoS) fluctuation while maintaining the minimum throughput required for a Web service. The proposed scheduler adjusts a trade-off between the degree of QoS fluctuation and the throughput according to the observed Round-Trip-Time (RTT). The authors implemented the proposed scheduler and evaluated its QoS by actual experiments. The results show that the proposed scheduler could adjust the trade-off between the QoS fluctuation and the throughput.

Study on Depending on the OpenFlow Controller Placement of Multi-pathization Method Reviewed International journal
Kaori Iwata, Yoshihiro Ito
Proceedings of 2019 IEEE 4th International Conference on Computer and Communication Systems (ICCCS) 712 - 715 2019.02
Language：English Publishing type：Research paper (international conference proceedings) Publisher：IEEE
This paper proposes a new method of improving multi-pathization method by only selecting the placement of OpenFlow controller. The performance of the multi-pathization is degraded by the difference in delay. The authors implemented their method by actual IoT devices and evaluate QoS by experiment. From the results of experiments, the TCP throughput when the location of the OpenFlow controller is appropriately selected is higher than that of multi-pathization method without our method. Thus, the proposed method decreases the difference in delay by replacing an OpenFlow controller adequately.

Study of Multi-Path TCP Scheduler to Suppress QoS Fluctuation for Improving WebQoE Reviewed International journal
Kensuke Noda, Yoshihiro Ito
Proceedings of IEIE/IEEE 2019 International Conference on Electronics, Information, and Communication (ICEIC) 2019.01
Language：English Publishing type：Research paper (international conference proceedings) Publisher：IEEE
This paper proposes a new packet scheduler of MPTCP to suppress Quality of Service (QoS) fluctuation for improvement of Quality of Experience for a Web service (WebQoE). The scheduler estimates the fluctuation of QoS from that of the packet delay, and preferentially sends a packet to uncongested path to suppress the fluctuation. The authors implement the proposed scheduler and evaluate QoS by experiments under various environments. From the results, they show that the proposed method deteriorates QoS but suppresses the fluctuation as compared with the default scheduler under various environments.
