Peer-To-Peer (P2P) file sharing applications, such as Napster and Gnutella supports millions of users to search and download desired data. Replication strategies are extensively utilized to improve search performance in unstructured P2Ps. To address the problems of the query popularity independent replication strategies, previously a novel strategy, called BloomCast that implements bloom filters in WP (With Pointers) scheme to support efficient and effective full-text retrieval over unstructured p2p networks was developed. BloomCast hybridizes a lightweight DHT with an unstructured P2P overlay to support random node sampling and network size estimation.
