Abstract

Wireless universal serial bus (WUSB) is the USB technology merged with WiMedia PHY/MAC. WUSB can be applied to wireless persanal area network (WPAN) applications as well as PAN applications like wired USB. Because numerous WUSB networks operate independently for each application, data conflict can occur between adjacent networks. To avoid data conflict, the resource in a different time zone can be utilized. However, if devices in a network increase, available resources in the network decrease, and then the lack of resources necessary to provide service can occur. To solve this problem, we propose interference avoidance scheme for WUSB systems.

무선 USB (universal serial bus) 시스템은 기존의 USB 기술과 WiMedia PHY/MAC 기술을 결합한 새로운 기술이다. 무선 USB 시스템은 기존의 USB와 같은 개인 영역 네트워크 뿐만 아니라 무선 개인 영역 네트워크에서도 적용될 수 있다. 다수의 무선 USB 네트워크들은 각각의 어플리케이션을 위해 독립적으로 형성되고 동작할 수 있기 때문에, 인접한 네트워크간 간섭이나 충돌이 발생할 수 있다. 이러한 문제를 해결하기 위해, 슈퍼프레임내 다른 시간 구간을 이용하는 방법을 사용할 수 있다. 하지만, 네트워크의 수가 많아지게 되면, 이용 가능한 자원이 부족하게 된다. 따라서, 본 논문은 무선 USB 시스템을 위한 간섭회피 기법을 제안한다.
