초록

본 논문에서는 WiMedia D-MAC 기술 기반 Wireless USB 프로토콜에서 분산적인 SoQ기반 Wireless USB Channel 자원 할당 방법의 성능을 분석하고, QoS 성능 향상을 위해 릴레이 통신 기술을 적용한 SoQ 릴레이 전송 프로토콜을 제안한다. 본 논문에서 제안하는 SoQ 릴레이 전송 프로토콜은 Satisfaction of QoS (SoQ) 알고리즘을 각 단말 디바이스 내 WiMedia D-MAC 계층에서 분산적으로 실행하고, 충돌대상 디바이스에게 예약된 QoS 자원을 유지할 수 있도록 Direct Link 뿐만 아니라 릴레이 노드를 경유하여 또 다른 Indirect Link 링크를 예약할 수 있는 자원 예약 프로토콜을 제안한다.

The WiMedia Alliance has specified a Distributed Medium Access Control (D-MAC) protocol based on UWB for high speed wireless home networks and WPANs. In this paper, firstly, the fair SoQ-based Distributed Reservation Protocol (DRP) for D-MAC is analyzed. And a novel SoQ-based relay transmission protocol is proposed to overcome DRP conflicts fast. In the proposed protocol, each device executes the Satisfaction of QoS (SoQ) time slot allocation algorithm independently. And, in order to give the loser device due to DRP conflicts another chance to maintain QoS resources, the proposed relay transmission protocol helps the device reserve another indirect link maintaining the required QoS resources via a relay node.
