Abstract: This paper proposes a resource discovery model by forming matchmaking engines into P2P overlay, which employs both resource matching technology and P2P technology, thus matching semantics and scalability can be achieved. Simulation tests demonstrate that the proposed model is naturally appropriate to the organization-based nature of grid, capable of discovering matching resources efficiently and accurately.

摘要： 提出一种基于匹配引擎覆盖网络的网格资源发现模型，该模型融合资源匹配技术与P2P定位方法的各自优势，既保证了丰富的资源匹配语义，又解决了资源定位的可扩展性问题，能够满足网格环境下多自治组织的资源发现需要。仿真实验发现，该模型能够快速准确地发现匹配资源，提高了网格资源发现的容错性、健壮性和可扩展性。
