Efficient Range Query Processing in Peer

Abstract With the increasing popularity of the peer-to-peer P2P computing paradigm many general range query schemes for distributed hash table DHT -based P2P systems have been proposed Although those schemes can provide range query capability without modifying the underlying DHTs they have the query delay depending on both the scale of the system and the size of the query space or...

An Introduction to Peer

Jan 06 2021 0183 32 However with peer-to-peer data streaming and processing using the LabVIEW FPGA Module you can create a frequency-domain trigger In the application depicted in Figure 2 the PXIe-5663 vector signal analyzer uses peer-to-peer streaming to send data to the FlexRIO FPGA module where it is windowed converted to the frequency domain and then...

A Stable Approach for Routing Queries in Unstructured P2P

Jan 05 2016 0183 32 Abstract Finding a document or resource in an unstructured peer-to-peer network can be an exceedingly difficult problem In this paper we propose a query routing approach that accounts for arbitrary overlay topologies nodes with heterogeneous processing capacity eg reflecting their degree of altruism and heterogenous class-based likelihoods of query resolution at nodes which may reflect...

Accuracy of Aggregation in Peer

Abstract Peer-to-peer routing mechanisms are resilient to churn in the overlay network layer A major challenge for peer-to-peer database man-agement systems is to provide similar robustness in the data and query processing layer In this paper we in particular study aggregation queries and present a new approach to increasing accuracy of...

Robust and efficient aggregate query processing in peer

The ability to approximately answer aggregation queries accurately and efficiently is of great benefit for decision support and data mining tools A P2P network consists of numerous peer nodes that share data and resources with other peers on an equal basis Unlike traditional client-server models no central coordination exists in a P2P system thus there is no central point of failure...

Survey of Advanced Search in P2P Networks

Abstract As Peer-to-Peer P2P networks grow in popularity the ease accuracy and efficiency of search for resources stored in the network has become one of the determining factors in the adaptation of any P2P networkDifferent P2P networks use different overlay schemes and thus a same model of search is not going to be efficient in all the P2P networks...
