Ontology-based peer exchange network(OPEN)

Peer-to-peer systems represent a widely accepted approach to sharing massive data and services among large, diverse and varying sets of nodes in the network. In this paper, we introduce an overlay network which constructs the logical network topologies using a global ontology and peer ontological characteristics. Network construction and query model are defined to allow the efficient answer of complex queries based on concepts and relations. Simulation results are used to verify the predicted network properties.
