P-Chord:an Partition-Based Routing Model for Chord

In P2P network, a fundamental problem that confronts peer-to-peer application is to efficiently locate the node that stores a particulat data item.The routing table in Chord suffers serious information redundancy and affects the efficiency of the system. So, an partition-based routing model for Chord (P-Chord) is proposed. By partition, the routing table of nodes are improved to depress information redundancy and gain more useful information. Simulation experiments show that P-Chord reduces the average lookup path length and gets higher efficiency under the condition of keeping other Chord performance.
