Abstract

In this paper, firstly, performance degradation due to the Private Distributed Reservation Protocol (DRP) conflict problem caused by devices' mobility is analyzed. And a novel relay transmission protocol combined with Private DRP conflict resolution is proposed to overcome the performance degradation at Private DRP conflicts. In order to give the loser device due to Private DRP conflicts another chance to maintain resources, the proposed relay transmission protocol executed at each device helps the loser device reserve another indirect link maintaining the required resources via a relay node.

본 논문에서는 UWB 기술 기반 무선 USB(WUSB) 프로토콜에서, 디바이스들의 이동성으로 인해 발생하는 Private Distributed Reservation Protocol (DRP) 예약 충돌 현상을 분석한다. 그리고 Private DRP 예약 충돌 시 발생하는 성능 저하를 감소시키기 위해 Private DRP 릴레이 통신 기술을 제안한다. 본 논문에서 제안하는 Private DRP 릴레이 통신 프로토콜은 충돌대상 디바이스에게 예약된 자원을 유지할 수 있도록 Direct Link 뿐만 아니라, Private DRP 예약 충돌 시 릴레이 노드를 경유하여 또 다른 Indirect Link 링크를 빠르게 예약할 수 있는 분산적인 자원 예약 프로토콜을 제안한다.
