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 …
