SEARCH METHOD FOR AN UNSTRUCTURED P2P NETWORK

摘要

The present invention provides a search method for an unstructured P2P network, comprising the steps of: selecting a subset of its neighbours adaptively in the unstructured P2P network by a querying peer; forwarding a Query message to the subset of its neighbours intelligently on the basis of a search criteria by the querying peer; and returning a QueryHit message to the querying peer in response to the Query message by a receiver peer, if the receiver peer in the subset of the querying peer's neighbours can provide a reply; otherwise, propagating the Query message to one of its neighbours having the most probability to respond to the Query message with a QueryHit message by the receiver peer.
