해양 통신 네트워크에서 안정적 통신을 위한 HARQ-ARQ interaction 기법의 성능 평가

Abstract

As the wireless communication technologies are being studied for application to marine communication networks in a fusion of marine industries and IT technology, this paper proposes a HARQ-ARQ interaction scheme for reliable communication between the smart ships. Moreover, this paper evaluates the performance of the HARQ-ARQ interaction schemes through the computer simulation. In the HARQ-ARQ interaction scheme for marine network systems, as a HARQ acknowledgement is implicitly utilized as an ARQ acknowledgement. Hence, the HARQ-ARQ interaction scheme can reduce the packet delay. However, the HARQ-ARQ interaction scheme has problems caused by the error of HARQ feedback messages. Hence, this paper considers the effect of error of HARQ feedback messages on the performance of the HARQ-ARQ interaction scheme, in marine network systems. The simulation results show that the HARQ-ARQ interaction scheme can improve the delay performance of the ships in the marine network systems. 논문 14-39C-11-25 The Journal of Korean Institute of Communications and Information Sciences '14-11 Vol.39C No.11 http://dx.doi.org/10.7840/kics.2014.39C.11.1201 1201 ※ 본 연구는 미래창조과학부 및 정보통신산업진흥원의 IT융합 고급인력과정 지원사업의 연구 결과로 수행되었음(NIPA-2014-H0401-1 4–1009). 그리고 2012년도 정부(미래창조과학부)의 재원으로 한국연구재단의 지원을 받아 수행된 연구임(No. 2012R1A2A2A01012 059).
