Abstract:
Searching and organization of peers are
fundamental challenges in P2P networks. Unstructured
networks, such as Gnutella, inefficiently use broadcast
searches and random neighbors. Structured networks
are similarly inefficient, as they generally rely on
globally unique identifiers (GUIDs) which are
assigned irrespective of content, which prevents fuzzy
semantic searches. In both types of network search,
neighbors establish trust between themselves,
regardless of whether or not their content is likely to
satisfy searches. We present the idea of using contextbased
profiles to describe peers. This enables selforganizing
clusters of similar peers. A profile
represents a peer?s expertise based on content and
responsiveness. By refining the search process using
these profiles, more efficient directed searches are
possible. Moreover, expertise provides a basis for trust
establishment.
