초록

본 논문에서는 선박 내 IT 서비스에 대한 요구에 부응하기 위해 적응적이고 합리적으로 무선 주파수를 활용하는 인지무선 최초 표준인 ECMA-392 네트워크를 사용한다. ECMA-392 네트워크를 이용한 선박 내 멀티 홉 무선브릿지에서 멀티미디어 서비스를 지원하기 위한 QoS를 보장하는 ECMA-392 협력 MAC 프로토콜을 제안한다. 제안하는 프로토콜은 ECMA-392 장치들 사이의 정보를 바탕으로 효율적인 경로를 선택하여 직접 전송을 하거나 릴레이 전송을 하기 때문에 장치의 QoS를 보장하는 통신을 제공한다. 시뮬레이션 결과는 제안된 협력 MAC 프로토콜이 기존의 방식에 비해 데이터 수율을 향상 시키고 있음을 나타낸다.

In this paper, we use the ECMA-392 standard, the first cognitive radio networks to meet the demand for IT services in the ship. We propose a ECMA-392 cooperative MAC protocol to ensure QoS to support multimedia services in the ship area in a multi-hop wireless bridge using ECMA-392 networks. Because the proposed protocol transmits directly or relay transmission by selecting efficient routes based on the information of the ECMA-392 devices, it provides communication to ensure QoS of the device. The simulation results show that the proposed cooperative MAC protocol improves a throughput of devices compared to the existing method.
