an adaptive index allocation scheme for reliable data retrieval and provision in peer-to-peer networks
File-sharing Peer-to-Peer systems are effective for autonomous data retrieval and provision over the networks. However, the previous data retrieval schemes such as Gnutella and Local Indices have bad performance and large overhead. In order to solve these drawbacks, this paper proposes an adaptive scheme for data retrieval and provision, in which indices are dynamically allocated in appropriate nodes adaptively to variation of traffic patterns caused by query messages. The simulation experimental results show that the proposed scheme has good performance with reasonable overhead even when the traffic patterns vary as time proceeds.
