Abstract

We propose a peer-to-peer search scheme in which super peers with high rapacity constitute a ring by themselves and all peers utilize the ring for their query and publishing keys. In a dynamic peer-to-peer environment, the size of the super peer ring changes adaptively according to the changes of the system, but more powerful peers are continuously promoted to super peers. By simulations, we show that our proposed search scheme improves the query success rate of Gnutella+1hop replication search method, and maintains shorter query delay than JXTA as a static ring.

본 논문에서는 비구조적 피어-투-피어 시스템에서의 낮은 검색 성공률과 긴 검색 시간을 개선하기 위하여, 성능이 우수한 우수 피어들로 자기 조직적인 링 구조를 구성하고 광고 및 검색에 이용하는 검색 기법을 제안하였다. 우수 피어 링 구조는 동적인 환경에서 시스템의 상황에 따라 적응적으로 크기가 변하고, 에이전트를 이용하여 지속적으로 우수한 피어들이 링 구조에 참여하게 함으로써 성공률을 높이고, 빠른 검색 시간을 유지할 수 있게 하였다.
