According to the deficiency of Chord algorithm supporting single keyword queryonly, a P2P framework-HilbertChord by combining the Hilbert curve and Chord is proposedfor managing grid service resources, which supports DHT-based multi-keyword query andapproximate query by means of Hilbert index to improve resources searching ability.Experiments show that HilbertChord has better efficiency and scalability for managingservice resources under the large scale P2P environment with higher density of services.
