A Resource Discovery Algorithm Based on P2PGrid

In order to improve the dynamic and scalability of grid, the paper adopts the way fusing P2P and Grid organically, which resolves the issue that the node can join randomly and the resource-sharing can be dynamic in gird. This paper builds a resource architecture model based on P2PGrid and proposes a resource discovery algorithm fusing DHT and ant colony algorithm. This algorithm can accurately and reliably develop distributed resource discovery with high credibility value and low integrated cost, which can effectively improves resource discovery performance under the P2PGrid environment.
