Abstract

In this paper, we use the ECMA-392 standard, the first cognitive radio networks to meet the demand for IT services in the ship. First, we learn about ECMA-392-based network and examine the consideration and the problems for assigning channels to the device. And, we propose a fair channel resource allocation to ensure efficiently channel required by device groups in ECMA-392 MAC protocol. This is a method to reallocate the channels fairly with considering the channel assignment parameters to a new device group and existing device groups. The simulation results show that the proposed scheme improves throughputs compared to the existing one.

본 논문에서는 선박 내 IT 서비스에 대한 요구에 부응하기 위해 적응적이고 합리적인 무선 주파수를 활용하는 인지무선 기술 중 최초 표준인 ECMA-392 네트워크를 사용한다. 먼저, ECMA-392 기반 네트워크에 대해서 알아보고, 디바이스에게 채널 할당을 위한 고려사항 및 문제점을 살펴본다. 그리고, ECMA-392 MAC 프로토콜에서 디바이스 그룹들이 요청하는 채널을 효율적으로 보장하기 위한 공평한 채널 자원 할당 방법을 제안한다. 새로운 디바이스 그룹과 기존의 디바이스 그룹들에게 채널 할당 파라미터를 고려하여 공평하게 채널들을 재할당할 수 있는 방법이다. 시뮬레이션 결과는 제안된 방식이 기존의 방식에 비해 데이터 수율을 향상시키고 있음을 나타낸다.
