In order to provide enough level of QoE (quality of experience) to more applications with more importance operating on a shared frequency band, we have proposed a QoE-oriented wireless LAN system. Its radio resource management and channel access control are performed based on QoE sufficiency with the aid of spectrum sensing. This paper proposes an use case of the proposed system, which is named "evacuation center in wide-scale disaster." This paper also proposes QoS (quality of service)-QoE transform functions and traffic models of three major applications in this use case, i.e., accelerometer, video distribution and online game. Assuming this use case and IEEE 802.11g ERP-OFDM, it is confirmed through computer simulation that the proposed system can improve the QoE sufficiency of the video distribution application and the total throughput which contributes to satisfy the required QoE by 20% compared with the conventional wireless LAN. |
