Query processing is the next step after the query routing task Specifically, after the query is routed to a set of appropriate peers, query processing undertakes the task of combining the results from each peer and returning the final ones to the peer that submitted the original query In this work, we focus on query processing for top-k queries
In mobile ad hoc peer to peer (M-P2P) networks, since nodes are highly resource constrained, it is effective to retrieve data items using a top-k query, in which data items are ordered by the score of a particular attribute and the query-issuing node acquires data items with the k highest scores However, when network partitioning occurs, the query-issuing node cannot connect to some nodes having data …

a) In pure peer-to-peer network peers act as equals, merging the roles of clients and server In such networks, there is no central server managing the network, neither is there a central router Some examples of pure P2P Application Layer networks designed for peer-to-peer file sharing are gnutella (pre v04) and Freenet
Peer-to-peer (P2P) systems have the advantage of high autonomy However, query processing in P2P system is inefficient because query messages propagate in the P2P network To realize efficient and scalable systems without losing the autonomy of the P2P system, this paper proposes an index system called direct indices (DIs) in which the indexes keep information about the usefulness of peers and
