  • Approximate Queries in PeertoPeer Systems |

    Peertopeer (P2P) networks enable the interconnection of a huge amount of information sources without imposing costs for a central coordination infrastructure Due to the dynamic and selforganizing nature of such networks, it is not feasible to guarantee completeness and correctness as in traditional distributed databases Therefore, P2P systems are usually appliedThe ability to approximately answer aggregation queries accurately and efficiently is of great benefit for decision support and data mining tools A P2P network consists of numerous peer nodes that share data and resources with other peers on an equal basis Unlike traditional clientserver models, no central coordination exists in a P2P system; thus, there is no central point ofRobust and efficient aggregate query processing in peer
