본 논문에서는 IEEE 802.11e HCCA를 이용한 오디오-비디오 전송에서 QoS 지원을 위한 교차 계층 패킷 스케줄링 방식을 제안하고 손실 채널 조건에서 스케줄링 방식의 애플리케이션 수준 QoS 및 QoE를 평가합니다. 제안된 계획에서는 액세스 포인트(AP) 기본적으로 할당 전송 기회(TXOP) 각 역마다 서비스 간격(SI) 본 문서에서는 TGe 방식이라고 하는 IEEE 802.11e 표준의 참조 스케줄러와 같습니다. 그러나 제안된 방식에서는 AP가 MSDU(MAC 서비스 데이터 단위) 오디오 샘플의 도착 간격과 비디오 프레임의 도착 간격 시간을 고려하여 SI에 도착합니다. 미디어 유닛(MU), 애플리케이션 계층에서. 그런 다음 AP는 오디오 또는 비디오가 있는 스테이션에 SI의 추가 TXOP 기간을 제공합니다. MAC 프로토콜 데이터 단위(MPDU) 이전 TXOP가 끝날 때 소스 버퍼에 있습니다. 또한, 애플리케이션 계층의 비디오 프레임 정보를 활용하여 소스 스테이션의 MAC 수준에서 비디오 프레임 건너뛰기를 제안합니다. 스테이션이 비디오 MPDU 전송에 실패하면 다음 인트라 코딩된 프레임이 버퍼의 헤드에 올 때까지 소스 버퍼의 다음 비디오 MPDU를 모두 삭제합니다. 우리는 애플리케이션 레벨 QoS 및 QoE 측면에서 소스에서 비디오 프레임 건너뛰기를 포함하는 것과 포함하지 않는 제안된 패킷 스케줄링 방식인 참조 스케줄러(TGe 방식)를 비교합니다. 제안하는 패킷 스케줄링 기법의 효율성을 QoE와 QoS 관점에서 논의한다. 수치적 결과는 제안된 패킷 스케줄링 방식이 손실 채널 조건에서 TGe 방식보다 더 높은 품질을 달성할 수 있음을 보여줍니다. 또한 제안된 스케줄링 기법이 소스에서 비디오 프레임 건너뛰기를 사용하여 QoS 및 QoE를 향상시킬 수 있음을 보여줍니다. 또한 제안된 패킷 스케줄링 기법의 QoS 및 QoE에 대한 SI의 영향을 검토하고 SI의 적절한 값이 비디오 프레임의 도착 간 시간과 동일하다는 것을 얻습니다.

Abstract: This paper proposes a cross-layer packet scheduling scheme for QoS support in audio-video transmission with IEEE 802.11e HCCA and assesses application-level QoS and QoE of the scheduling scheme under lossy channel conditions. In the proposed scheme, the access point (AP) basically allocates transmission opportunity (TXOP) for each station in a service interval (SI) like the reference scheduler of the IEEE 802.11e standard, which is referred to as the TGe scheme in this paper. In the proposed scheme, however, the AP calculates the number of MAC service data units (MSDUs) arrived in an SI, considering the inter-arrival time of audio samples and that of video frames, which are referred to as media units (MUs), at the application layer. The AP then gives additional TXOP duration in the SI to stations which had audio or video MAC protocol data units (MPDUs) in their source buffers at the end of the previous TXOP. In addition, utilizing video frame information from the application layer, we propose video frame skipping at the MAC-level of a source station. If a station fails to transmit a video MPDU, it drops all the following video MPDUs in the source buffer until the next intra-coded frame comes to the head of the buffer. We compare the reference scheduler (TGe scheme), the proposed packet scheduling scheme with and without the video frame skipping at the source in terms of application-level QoS and QoE. We discuss the effectiveness of the proposed packet scheduling scheme from a viewpoint of QoE as well as QoS. Numerical results reveal that the proposed packet scheduling scheme can achieve higher quality than the TGe scheme under lossy channel conditions. We also show that the proposed scheduling scheme can improve the QoS and QoE by using the video frame skipping at the source. Furthermore, we also examine the effect of SI on the QoS and QoE of the proposed packet scheduling scheme and obtain that the appropriate value of SI is equal to the inter-arrival time of video frame.
