Peano Space Filling Curve Applied in Managing P2P Service Resources

According to the deficiency of Chord algorithm supporting single keyword query only, a P2P framework-Peano Chord (PC) by combining the Peano and Chord is proposed for managing service resources, which combines Peano space filling curve and P2P Service Resources and supports DHT-based multi-keyword query and approximate query by means of Peano index to improve resources searching ability.
