Abstract:
A unstructured P2P network does searching by packet forwarding which has some problems: hit ratios are low, and the network is filled with packets. A structured P2P network based on the distributed hash table (DHT) solves these problems. However, it is restricted to keyword search. This paper proposes a P2P network which reorganizes itself dynamically, aiming at search efficiency of the structured P2P and the search flexibility of the unstructured P2P at the same time. We define similarity of contents based on the folksonomy in social networks, and make the network update its links dynamically based on the content similarities. By simulation-based experiments, we confirmed improvements of query hits in this P2P network.
