초록

본 논문에서는 디바이스의 이동으로 인한 WiMedia 네트워크의 성능 저하를 개선하기 위한 릴레이 통신 기법을 제안하였다. WiMedia 프로토콜은 고속의 전송속도를 지원하기 때문에, 선박 네트워크(Ship Area Network)등과 같은 환경에서 고속의 전송률을 요구하는 실시간 멀티미디어 서비스 제공과 같은 응용분야에 적합하다. 하지만, 디바이스의 이동은 네트워크 토폴로지와 디바이스간 링크 상태의 급격한 변화를 야기하며, 네트워크의 성능 저하의 원인이 되기도 한다. 본 논문에서는 기존의 WiMedia 프로토콜에서는 채널의 링크 상태 변화를 적절하게 대처하지 못하여 발생하는 네트워크 성능저하를 해결하는 릴레이 통신 기법을 제안하였다.

In this paper, a relay communication scheme for enhancing the WiMedia network performance by device's mobility is proposed. WiMedia 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 relay communication scheme for WiMedia network is proposed in this paper. The proposed technique can intelligently treat the change of link state, and solve the degradation of network performance.
