A framework for cascading payment and content exchange within P2P systems
… by the increased popularity of Peer-to-Peer (P2P) file-sharing networks. P2P is a viable and cost effective model for content distribution. Content producers require modest resources by today's standards to act as distributors of their content and P2P technology can assist in further reducing …

Data replication and update propagation in XML P2P data management systems
XML P2P data management systems are P2P systems that use XML as the underlying data format shared between peers in the network. These systems aim to bring the benefits of XML and P2P systems to the distributed data management field. However, P2P systems are known for their lack of central control …

A physically-aware architecture for self-organizing peer-to-peer overlay networks
Over the last few years Peer-to-Peer (P2P) systems have emerged as highly attractive systems supporting many useful large-scale applications and services. They allow the exploitation of enormous untapped resources (such as idle processing cycles, storage, and bandwidth) available at …

Schema matching in a peer-to-peer database system
Peer-to-peer or P2P systems are applications that allow a network of peers to share resources in a scalable and efficient manner. My research is concerned with the use of P2P systems for sharing databases. To allow data mediation between peers' databases, schema mappings need to exist, which are …

Volatility-Aware Query Processing in Peer-to-Peer Systems
Peer-to-Peer (P2P) paradigm has been recognized as a disruptive technology that can aggregate enormous storage and processing resources for information sharing and distributed computing. This paradigm has received significant attention in both academic and industry. However, most of the effort has …

Query Evaluation Techniques for Data Integration Systems
… query evaluation techniques for data integration systems in different environments, ranging from a central data-warehouse approach, over distributed virtual market places, to peer-to-peer (P2P) systems. Based on a new distributed evaluation technique, the so-called HyperQueries, we present a …

A NOVEL LINEAR DIOPHANTINE EQUATION-BAESD LOW DIAMETER STRUCTURED PEER-TO-PEER NETWORK
… interest-based overlay Peer-to-Peer (P2P) system. We have used Linear Diophantine Equation (LDE) as the mathematical base to realize the architecture. Note that all existing structured approaches use Distributed Hash Tables (DHT) and Secure Hash Algorithm (SHA) to realize their …

Evolutionary methods for self-organizing cooperation in peer-to-peer networks
… final users and researchers for its features. P2P networks shift from the classic client-server approach to a high level of decentralization where there is no central control and all the nodes should be able not only to require services, but to provide them to other peers as well. While on one …

A study of gossip algorithms for internet-scale cardinality estimation of distributed XML data
… research and development, the peer-to-peer (P2P) computing model continues to be successful. We have witnessed the deployment of commercial P2P applications in large, Internet-scale environments. With the rise and growth of P2P, indexing and querying data stored in large-scale sharing systems …

Managing child sexual exploitation material offenders: an exploration of investigative process, offending practise and a paraphilic profiling methodology for users of peer-to-peer systems
… sex offending and investigation in Peer-to-peer (P2P) networks in order to identify investigative and offence-related factors that may improve investigative capacity for the identification of online child sex offenders with problematic profiles. Furthermore, it develops the basis of an empirical …

A keyword-set search system for peer-to-peer networks
… Search System (KSS) is a Peer-to-Peer (P2P) keyword search system that uses a distributed inverted index. The main challenge in a distributed index and search system is finding the right scheme to partition the index across the nodes in the network. The most obvious scheme would be to …

A Framework for Digital Investigation of Peer-to-Peer (P2P) Networks. An Investigation into the Security Challenges and Vulnerabilities of Peer-to-Peer Networks and the Design of a Standard Validated Digital Forensic Model for Network Investigations
Peer-to-Peer (P2P) Networks have been presenting many fascinating capabilities to the internet since their inception, which has made and is still gathering so much interest. As a result, it is being used in many domains, particularly in transferring a large amount of data, which is essential for …

Trust management schemes for peer-to-peer networks
Peer-to-peer (P2P) networking enables users with similar interests to exchange, or obtain files. This network model has been proven popular to exchange music, pictures, or software applications. These files are saved, and most likely executed, at the downloading host. At the expense of this …

Indexing XML Data for Efficient Twig Pattern Matching
… stored and (b) a growingly popular peer-to-peer (P2P) environment. In a traditional enviroment, the index built over XML data is typicallycentralized. On the other hand, due to the distributed nature of the data in a P2P system, the index is also distributed. Due to the different models of storing …

On Reducing Delays in P2P Live Streaming Systems
In the recent decade, peer-to-peer (P2P) technology has greatly enhanced the scalability of multimedia streaming on the Internet by enabling efficient cooperation among end-users. However, existing streaming applications are plagued by the problems of long playback latency and long churn-induced …
