초록

본 논문에서는 WiMedia 프로토콜에서, 전송 효율을 높이기 위한 연쇄된 프레임 기법을 분석한다. 그리고 연쇄된 프레임에 포함되는 미니-프레임들중 일부 미니-프레임의 손실로 인해 발생하는 성능 저하를 감소시키기 위한 효율적인 전송기법을 제안한다. 본 논문에서 제안하는 전송 기법은 연쇄된 프레임에 포함되는 미니-프레임의 손실이 발생할 경우, 에러가 발생한 미니-프레임만을 재전송하여 전체적인 에너지 소모를 줄이고, 전송효율을 높일 수 있다. 이를 증명하기 위해, 본 논문에서는 제안된 기법을 시뮬레이터에 적용시켜서 성능 분석을 수행하였다.

In this paper, a concatenated frame algorighm for improving transmission efficiency in WiMedia protocol is studied. And an efficient transmission scheme to reduce the degradation of network performance by the loss of mini-frame is proposed in this paper. The proposed scheme can reduce total energy consumption and improve the transmission efficiency since it only retransmits mini-frame in which error is occurred. The simulation results show that proposed protocol can enhance the throughput performance and improve energy efficiency by minimizing the retransmission of mini-frame.
