초록

본 논문에서는 다중 선박으로 구성된 해양 네트워크에서 선박 간 통신 거리를 확장하면서 전송률을 향상시키는 양방향 다중-홉 릴레이 기법을 제안한다. 제안 기법은 두 단계 디지털 네트워크 부호화를 기반으로 각 선박의 데이터 전송 순서와 네트워크 부호화 순서를 알맞게 설계하여 데이터 교환에 필요한 시간 슬롯 수를 줄인다. 모의실험 결과 제안하는 양방향 다중 홉 릴레이 기법은 기존 기법의 전송률을 약 5/3배 향상시킴을 볼 수 있다.

We propose a two-way multi-hop relaying scheme improving the throughput as well as enlarging the coverage for ship-to-ship communications in multi-ship marine networks. The proposed scheme reduces the time slots required for the data exchange by designing data transmission and network coding procedures in a sophisticated way based on two-phase digital network coding. Simulation results show that the proposed two-way multi-hop relaying scheme improves the throughput of the conventional one about 5/3 times.
