CDMA2000 1xEV-DO 이동통신 망에서 일대일 주문형 비디오 서비스를 위한 비디오 트레이스 기반 무선 MAC 스케줄러 = A Wireless MAC Scheduler based on Video Traces for One-to-one Video-on-demand Services in CDMA2000 1xEV-DO

국문 초록 (Abstract)

CDMA2000 1xEV-DO 이동통신 시스템에서 주문형 비디오 서비스를 고품질로 제공하면서도 합리적 수준의 시스템 성능을 제공하는 무선 MAC 스케줄러를 제안한다. 제안하는 스케줄러는 응용 계층에 존재하는 비디오 데이터 정보를 MAC 계층에 존재하는 스케줄러가 활용하여 주문형 비디오 서비스의 품질이 개선되도록 한다. 우리는 시뮬레이션 실험을 통해서 제안하는 방식이 이전에 제안된 비디오 트레이스 방식과 비교 했을 때 VBR(Variable-Bit-Rate) 비디오의 비디오 프레임 변화가 클수록 더 뛰어난 품질과 성능을 제공함을 보인다.

다국어 초록 (Multilingual Abstract)

A wireless MAC scheduler for CDMA2000 1xEV-DO that provides a high level of quality-of-service(QoS) for video-on-demand(VOD) applications while achieving a reasonable level of system throughput is proposed. The proposed scheduler that exists in the MAC layer utilizes the video data information that resides in the application layer such that it improves the QoS for VOD applications. We show by simulations that our approach is better than the previous scheduler which is also based on video traces for VBR videos that have high variability between video frames.
