摘　　要：网格资源发现是网格研究中的重要组成部分,随着P2P网络的兴起,许多新的概念和研究方向为网格研究提供了思路.该文在分析了现有网格资源查找方式不足的基础上,提出了一种基于P2P分层结构的网格资源发现模型.模型针对网格资源的特点引入了本体和语义相关度概念,在此基础上将网格资源进行分层管理,并借鉴了iVCE体系结构,提出了本体共同体的概念从而较好解决了虚拟组织内节点的动态自组织问题,较好实现了网格资源的聚合以及动态增减问题.Grid resource discovery is an importance part in grid research. New ideas are introduced to grid with the development of P2P system. Base on analyzing the lacks of existing methods in grid resource discovery, a grid resource discovery model based on P2P layered topology is proposed in this paper. The concept of ontology and semantic correlation are introduced and the grid resource is managed through layered method. The concept of ontology community is proposed based on the architecture of iVCE. The problem of dynamic self-organization among nodes can be solved well. The problem of polymerization and changes in the dynamic can also be achieved.
