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

Supporting Efficient Recursive Query Processing In Dhts

Abstract although various approaches have been proposed to process complex queries such as range queries join queries aggregate queries and etc in peertopeer data management research we find currently there are no efficient techniques to support linear recursive queries which is also one indispensable types of queries and exhibits crucial importance in many scenarios

Handbook Of Peertopeer Networking Xuemin Sherman

Peertopeer networking is a disruptive technology for large scale distributed app cations that has recently gained wide interest due to the successes of peertopeer p2p content sharing media streaming and telephony applications there are a large range of other applications under development

Peer To Peer File Sharing Database Project Source Code In

Peertopeer Systems October 2010 Communications Of

Peertopeer p2p computing has attracted significant interest in recent years originally sparked by the release of three influential systems in 1999 the napster musicsharing system the freenet anonymous data store and the setihome volunteerbased scientific computing projects

Aggregate Data With Xquery Oracle Magazine

Displaying the results the xquery expression shown in listing 5 can be passed on as an ad hoc query to oracle xds or the query can be stored for reuse you can store the xquery expression in listing 5 and then execute it by using one of the oracle xds client apis java client api jsp

Ieee Transactions On Parallel And Distributed

Its broadcast if q is a duplicate peer p drops the query else peer p sends results from its local file index to peer qif the query qs ttl has not yet expired qttl gt 0 then peer p forwards the query q with its ttl decremented by 1 to all its neighbors except peer q fig 1 provides a sketch of query processing in broadcaststyle

Definition Of Aggregate Query Processing

Definition of aggregate query processing aggregate analytic window query over spatial data and propose techniques to answer the query in spatial databases with different indexes such as grids and quadtree different various types of aggregate analytic queries may have different aggregate functions

Aggregate Query Processing In The Presence Of Duplicates

Using the peertree as a building block we present a peertopeer query processing model where a query can be posed in any node of the network without the need of a central server

Olap Query Reformulation In Peertopeer Data

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

Gossipbased Reputation Aggregation For Unstructured

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

Top K Query Processing In Mobilep2p Networks Using

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

An Introduction To Peertopeer Networks

A Knowledgebased Approach To Multiplayer Games In Peer

Dec 12 2018nbsp018332multiplayer computer games frequently rely on centralised clientserver solutions with limited scalability and a single point of failure replicating servers and performing loadbalancing mitigate some issues but create other problems like synchronising information among servers and controlling network traffic in this paper we present a fully distributed peertopeer approach to

Improving Search In Peertopeer Networks

Network nodes spend processing resources ie cycles to forward the query process it etc and bandwidth to send and receive messages the main cost of queries are therefore bandwidth and processing since the cost of a query is not incurred at any single node in the network it makes sense to discuss costs in aggregate ie overall the
