Abstract

A recent major development in computer technology is the advent of the wearable computer system that is based on human-centric interface technology trends and ubiquitous computing environments. Wearable computer systems can use the wireless universal serial bus (WUSB) that refers to USB technology that is merged with WiMedia PHY/MAC technical specifications. In this paper, we focus on an integrated system of the wireless USB over the IEEE 802.15.6 wireless body area networks (WBAN) for wireless wearable computer systems supporting U-health services. And a communication structure that can differentiate QoS of U-health WBAN and WUSB traffic with different priorities is proposed for WUSB over IEEE 802.15.6 hierarchical protocol. In our proposal and performance evaluation, throughputs of U-health WBAN and WUSB traffic are analyzed under single and multiple QoS classes to evaluate the effectiveness of proposed QoS differentiating structure in WUSB over IEEE 802.15.6.

최근 컴퓨터 기술의 발전으로 웨어러블 컴퓨터 기술이 개발되고 있다. 이는 HCI (human-centric interface)기술과 유비쿼터스 컴퓨팅 기술을 기반으로 한다. 웨어러블 컴퓨터 시스템은 WiMedia PHY/MAC 기술과 결합된 USB 기술로 WUSB (wireless universal serial bus) 기술을 사용하여 구성할 수 있다. 본 논문은 U-Health 기능을 지원하는 무선 웨어러블 컴퓨터시스템을 구성하기 위해 WUSB기술과 IEEE 802.15.6 WBAN (wireless body area networks) 기술을 결합한 통신시스템 구조에 초점을 맞추었다. 그리고 IEEE 802.15.6 기반 WUSB 통신 구조에서 서로 다른 전송 우선 순위를 갖는 U-health WBAN 트래픽 및 WUSB트래픽의 QoS를 차등화하기 위한 통신 구조를 제안하였다. 제안내용 및 성능 평가에서는 단일 클래스 및 다중 클래스 환경에서 U-health WBAN 및 WUSB 트래픽의 수율 성능을 분석하여, WUSB over IEEE 802.15.6 통신구조에서 QoS 차등화 효율성을 평가하였다.
