초록

본 논문에서는 선박 내 IT 서비스에 대한 요구에 부응하기 위해 WiMedia WLP 기반의 네트워크를 사용한다. 이동 단말이 새로운 서브네트워크의 혼잡한 기지국으로 이동한 경우, 기존의 통신 중인 이동 단말들의 무선링크이용률 성능을 향상시키기 위한 방안을 제안한다. 이전 기지국은 핸드오버 동안 저장한 패킷들을 표기하고 혼잡한 새로운 기지국에서 버퍼의 혼잡정도에 따라 버퍼링 된 패킷의 폐기 유무를 결정한다. 다양한 시뮬레이션 시나리오에서 실시한 시뮬레이션 결과로부터 제안한 핸드오버를 고려한 버퍼관리 방식은 기지국의 혼잡한 무선링크에서 링크이용률을 향상시킬 수 있음을 확인한다.

In this paper, we use WiMedia WLP-based networks to meet the demand for IT services of a ship. If a mobile node moves to a congested base station of a new subnetwork, we will propose a scheme for improving performance of radio link of existing communicating mobile nodes. An old base station denotes packets stored during a handover. And, a proposed buffer management determines to discard the buffered packets in accordance with congestion degree at the congested new base station. Simulation results show that the proposed buffer management scheme improves link utilization in congested wireless links.
