Abstract

In this paper, we will provide a way to grant a differentiated service rate that is according to priorities of WLP device and WUSB/DRD transfer mode by improving D-SoQ that considers existing QoS of WiMedia WSS environment based on UWB technology. The proposed method makes it possible to differentiate SoQ performance and throughput, based on priority of traffic streams.

본 논문에서는 선박 내 UWB 기술 기반 WiMedia WSS 환경에서 WLP 디바이스와 WUSB/DRD 전송 모드의 우선순위에 따른 전송대역폭 자원 할당 방법을 제안한다. 기존의 QoS를 고려한 D-SoQ 방식은 동일한 데이터 전송률을 가져도 우선순위에 따른 스트림에게는 역차별을 가져오는 문제가 발생한다. WLP 디바이스와 WUSB/DRD 전송 모드의 우선순위에 따른 차등화된 서비스 전송률을 부여하는 제안하는 방법은 트래픽 스트림의 우선순위에 따라 수율 및 SoQ 성능의 차등화를 가능하게 한다.
