A semantic-based P2P resource organization model R-Chord

This paper proposes a semantic-based P2P resource organization model R-Chord by incorporating the Resource Space Model (RSM), the P2P Semantic Link Network Model (P2PSLN) and the DHT Chord protocol. Peers provide services with each other according to the content of their resources and the related configuration information. It incorporates the classification semantics and the relational semantics to provide users and applications with a uniform view on distributed resources. Experiments show that, compared to the Chord approach, the R-Chord approach is more flexible to support semantic-based queries and can significantly decrease the average visiting number of and visiting times on peers for answering queries.
