초록

최근에 분산 환경에서 사용자 위주의 멀티미디어 서비스를 효율적으로 제공하기 위한 여러 가지 방법들이 제안되고 있다. 멀티미디어 데이터의 분산 서비스를 위해서는 QoS 향상, 스트리밍 그리고 동적 서비스의 개선과 같은 문제점이 제기되고 있다. 본 논문에서는 분산네트워크 환경에서 사용자 위주의 서비스를 위한 $POX -H_{r}$구조를 제안하였다. 제안된 구조는 disjunct, conjunct, semantic 그리고 filtering에 의해 $POX -H_{r}$ 구조로 사상되며, 사상된 구조는 $M_{filtering}$에 의해 갱신된다. 비교분석 결과 제안된 기법의 성능이 보다 효율적임을 보인다.

Abstract

In recent years, several methods in distributed environment have been proposed in which a user-centered multimedia service may be efficiently provided. However, problems such as the improvement of QoS, streaming and the dynamic service of data for distributed service of multimedia data are introduced. In this paper we propose $POX -H_{r}$ structure for user-centered multimedia service in distributed network environment. The proposed $POX -H_{r}$ structure are constructed by disjunct, conjunct, semantic and filtering mapping scheme, and its structure are updated by $M_{filtering}$ scheme. The comparison results shows that the proposed method provides the better than the other methods.
