A peertopeer p2p data management system consists essentially of a network of peer systems each maintaining full autonomy over its own data resources data exchange between peers occurs when one of them in the role of a local peer needs data available in other nodes denoted the acquaintances of the local peer

This paper presents data exchange between peers occurs when one of them in the role of a local peer needs data available in other nodes denoted the acquaintances of the local peer and also an adaptive dualphase approach based on random walks of the p2p graph for efficiently serving range aggregate queries on data cubes in a peer to peer system

This work proposes the etop system for the efficient processing of topk queries in mobile ad hoc peer to peer mp2p networks using economic incentive schemesin etop brokers facilitate topk query processing in lieu of a commissionetop issues economic rewards to the mobile peers which send relevant data items ie those that contribute to the topk query result and penalizes peers

When a peer intends to query the global reputation of another peer it will broadcast the query message when a peer wants to report its feedbacks it will broadcast the reports this method will impose a lot of message in the network besides when network size is very large it will take a long time to disseminate peer reports and to get a

A network of superpeers superpeer networks strike a balance between the inherent efciency of centralized search and the autonomy load balancing and robustness to attacks provided by distributed search furthermore they take advantage of the heterogeneity of capabilities eg bandwidth processing power across peers which recent studies

Exchange of data and uses data synopsis techniques for minimizing the amount of data exchanged between pairs of nodes nodes maintain a xedsize array of entries and periodically exchange and accumulate information obtained from other peers previous work has focused on the diagnosis of individual aggregate values such as averages sums

Aggregate queries are disseminated via atree in topdown manner answers are gathered along its and parameters to all the nodes in the network peertopeer p2p computing has emerged as a power that require near realtime processing of aggregate queries over data stored across the overlay network examples

Aggregate query processing in peer to peer networks ering each node as a peer in a cooperative query system and allowing each peer a high degree of autonomy each node involved in the system dees a context where it becomes the local peer and all its dimensions and fact tables are considered local henceforth the rest of the nodes that connect with the local peer are considered acquaintances

Jul 01 2012nbsp018332in this direction a hybrid approach taking advantage of sampling techniques and approximate query processing to optimize performances for aggregate queries has been proposed in though the authors rely on a peertopeer network they neglect the issues related to the semantic heterogeneity that characterizes federated data warehouse systems

Doa adaptively grows the number of processing nodes as the sample size increases to further reduce the sampling overhead the samples are retained as a precomputed synopsis over the network to be used for processing future queries we also study how these synopsis can be maintained incrementally we have conducted extensive experiments on

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

The objective of our work is to select optimal sets of materialized aggregate views on different peers in a peer data warehousing system such that the total cost of answering the global queries posted on the given peer and maintaining the materialized views is minimized in this thesis we develop a theoretical framework for analyzing and
