A Field-Based Semantic P2P Overlay Network

This paper puts forward a field-based semantic P2P overlay network model. We applied the field theory to the overlay network construction. In the process of overlay construction, peers with identical semantic resources were connected together to form an equipotential line. The whole overlay network consisted of a certain amount of equipotential lines. In the process of query routing, the model would purposefully route the query to identical or similar equipotential lines according to the query semantic information. Then, only the peers on these equipotential lines would respond to the query. Results of simulated evaluation have shown that field-based semantic P2P overlay network could improve recall, accelerate query routing process, and reduce the number of messages in the network.
