본 문서에서는 안정적인 그룹캐스트 방식을 통해 무선 LAN을 통한 오디오 및 비디오 멀티캐스트 전송의 QoE를 향상시킵니다. 우리는 신뢰할 수 있는 그룹캐스트 방식으로 GCR(GroupCast with Retries) 원치 않는 재시도 및 GCR 블록 ACK를 사용합니다. IEEE 802.11aa에 의해 표준화되었습니다. 무선 액세스 포인트가 그룹캐스트를 통해 액세스 포인트에 연결된 여러 단말에 오디오 및 비디오 스트림을 전송한다고 가정합니다. 우리는 EDCA(Enhanced Distributed Channel Access)를 사용한 그룹캐스트, GCR 원치 않는 재시도 및 GCR 블록 ACK의 세 가지 방식을 비교합니다. 다양한 네트워크 조건에서 컴퓨터 시뮬레이션을 수행하여 애플리케이션 수준의 QoS를 평가하고 주관적인 실험을 통해 QoE를 평가합니다. 결과적으로 우리는 가장 효과적인 방식이 네트워크 상태에 달려 있음을 발견했습니다.

Abstract: This paper enhances the QoE of audio and video multicast transmission over a wireless LAN by means of reliable groupcast schemes. We use GCR (GroupCast with Retries) Unsolicited Retry and GCR Block ACK as reliable groupcast schemes; they are standardized by IEEE 802.11aa. We assume that a wireless access point transmits audio and video streams to several terminals connected to the access point by groupcast. We compare three schemes: Groupcast with EDCA (Enhanced Distributed Channel Access), GCR Unsolicited Retry and GCR Block ACK. We perform computer simulations under various network conditions to assess application-level QoS and evaluate QoE by a subjective experiment. As a result, we find that the most effective scheme depends on network conditions.
