Taxonomy-based routing overlays in P2P networks

In peer-to-peer network limited system resources prohibit broadcasting a query to all possible peers. Distributed hash table (DHT)-based approaches scale well, but do not consider ontological structures, such as existing classifications of peers in taxonomies. We investigate adaptive taxonomy-based routing overlays and present approaches for their automated computation. We propose taxonomy-based models and discuss how models are stored, queried and managed in a DHT-based catalog allowing an efficient taxonomy-based routing of queries in a peer-to-peer network.
