Abstract

In this paper, a resource management scheme for enhancing the network connectivity and reliability in wireless USB system is proposed. Wireless USB protocol is suitable for the application that supports the real-time multimedia service in Ship Area Network since it supports high speed data transfer. However, the device's mobility is caused the dramatic change of link state and network topology, and is occurred the degradation of network performance. Therefore, a resource management scheme for wireless USB system is proposed in this paper. The proposed technique can intelligently treat the change of link state, and solve the degradation of network performance. The simulation results show that proposed protocol can enhance the throughput and delay performance by selecting relay device with better link state.

본 논문에서는 무선 USB 시스템에서 신뢰성과 연결성을 향상하기 위한 기법을 제안하였다. 무선USB 프로토콜은 고속의 전송속도를 지원하기 때문에, 실시간 멀티미디어 서비스 제공과 같은 응용분야에 적합하다. 하지만, 디바이스의 이동은 네트워크 토폴로지와 디바이스간 링크 상태의 급격한 변화를 야기하며, 네트워크의 성능 저하의 원인이 되기도 한다. 특히 사람의 이동이 빈번한 선박 네트워크 환경에서는 디바이스의 이동성이 더 심해진다. 본 논문에서는 기존의 무선 USB 표준에서 무선 채널의 상태 변화를 적절하게 대처하지 못하여 발생하는 네트워크 성능 저하 문제를 해결하는 릴레이 통신을 위한 자원 관리 기법을 제안하여 성능을 분석하였다.
