Abstract

Link selection strategy has been an important technical issues of relay network. In this paper, we introduce a link selection scheme in the bidirectional, buffer-aided relay network. Three kinds of information such as the states of the queue at the relay buffer, the qualities of the links, and the states of the queues at the user buffer are considered. Throughput and delay performance is evaluated under three cases with different available information.

효과적인 링크선택은 릴레이 네트워크의 성능을 결정짓는 중요한 기술적 이슈이다. 본 논문은 릴레이 버퍼의 상태와 릴레이 링크 상태 뿐만 아니라 유저 버퍼의 상태까지 고려한 링크선택 방안을 제시하고 그 성능을 분석하기 위한 마코프 체인 기반의 분석 모델을 제시하였다. 이를 통해 릴레이 네트워크의 쓰루풋과 지연 성능을 평가하였다.
