摘　　要：为了解决网格技术中节点随机加入及资源动态共享的问题,采用了P2P与网格技术有机融合的方式,改进了网格的动态性和可扩展性,建立了基于P2P的网格资源体系结构模型,并提出了一种融合DHT和蚁群算法的资源发现算法.该算法能有效地提高P2P网格环境下的资源发现性能,可以准确可靠的进行信誉值高、综合费用低的分布式资源发现.In order to solve the problem that the node can be added randomly and the resource can be shared dynamically in grid, the paper .uses the organic integration method of P2P and grid, improves the dynamic and scalability of grid, builds grid resources architecture model based on P2P, and proposes a resource discovery algorithm based on DHT and ant colony algorithm. The algorithm can effectively improve resource discovery performance under the P2P Grid environment and can accurately and reliably perform.tbe distributed resource discovery with high credibility value and low composite expenses.
