To solve the Chord algorithm of P2P system only supporting single keyword precise query problem, we join the Hilbert curve into the Chord ring to form a new structure-HilbertChord (HC). It is a structure based on the Hilbert curve and Chord system. HC provides a good support for the approximate query. Experiments
bottleneck problem. P2P technology has been argued to have advantages in scalability and fault tolerance, nevertheless it is limited to support variable complex resource requirements to discover resources, mostly based on keyword or single attribute. In this paper, we propose a novel resource discovery model by organizing
and Ordinary peer. According to the model, this paper produces a novel Grid resource discovery algorithm, which adopts Keywords Mach algorithm based on Hash Table, employees TF_IDF to product resource keywords, locates and search s resource based on Consistent Hashing Chord, access lower latency and higher credibility
