Abstract

In this paper, we propose a multi-hop cooperative transmission protocol over Rayleigh fading channels. In the proposed protocol, the multi-hop cooperative transmission is used to improve the system performance. Due to broadcast nature, we do not limit the receiving node to be only the next node, but the destination and all the nodes between the transmitting node and the destination. The proposed protocol can hence save the average transmit power, compared with multi-hop direct transmission protocol due to the skipped transmissions from some intermediate nodes or chosen relays. The proposed scheme is implemented and evaluated in mobile ad-hoc wireless networks.

본 논문에서는 레일리 페이딩 채널의 멀티 홉 협력 전송 프로토콜을 제안한다. 제안된 프로토콜에서, 멀티 홉 협력 전송은 시스템 성능의 향상을 위해 사용되었다. 중계라는 특성으로 인해, 전송받는 노드와 다음의 노드뿐만 아니라, 목적지와 그 사이의 전송 받는 모든 노드들이 제한되어 있지 않다. 제안된 프로토콜은 선택된 릴레이나 몇몇의 중간 노드로부터 건너 뛰어 전송되는 멀티 홉 직접 전송 프로토콜에 비해 평균 전송 전력을 절약할 수 있다. 제안하는 기법은 모바일 ad-hoc 무선 네트워크에서 시행 및 평가되어진다.
