aggregate query processing in peer to peer networks 2013

Peer to Peer networks are used for distribution and sharing of documents In traditional techniques when aggregate functions like average sum and count are encountered the aggregate operation is performed by considering all the nodes and tuples which reduces the efficiency of the query processing system Exact solutions can be time consuming
