Data Distribution Management (DDM) deals with two basic problems: how to distribute data generated at the application layer among underlying nodes in a distributed system and how to retrieve data back whenever it is necessary. This thesis explores DDM in two different network environments: peer-to-peer (P2P) overlay networks and cluster-based network environments. DDM in P2P overlay networks is...

Recently, distributed computing system have been gaining much attention due to a growing demand for various kinds of effective computations in both industry and academia. In this paper, we focus on Peer-to-Peer (P2P) computing systems, also called public-resource computing systems or global computing systems. P2P computing systems, contrary to grids, use personal computers and other relatively ...

Peer-to-peer (P2P) computing has been hailed as a promising technology that will reconstruct the architecture of distributed computing (e.g., the Internet). This is because it can harness various resources (including computation, storage and bandwidth) at the edge of the Internet with lower cost of ownership, and at the same time enjoy many potential desirable features (e.g., scalability, auton...

Both Mobile Ad hoc Networks (MANETs) and Peer-to-Peer (P2P) networks are decentralized selforganizing networks with a dynamic topology, used to route queries in a distributed environment. However, whilst MANETs are composed of resource-constrained devices susceptible to faults, P2P networks are popular for their resilience and fault-tolerance. This makes P2P networks the ideal data sharing syst...

P2P Grids could solve large-scale scientific problems by using geographically distributed heterogeneous resources. However, a number of major technical obstacles must be overcome before this potential can be realized. One critical problem to improve the effective utilization of P2P Grids is the efficient load balancing. This chapter addresses the above-mentioned problem by using a distributed l...

In recent years, online social networks have become very popular. Online social networks (OSN) have been useful to find former classmates or to improve our interaction with friends. Thus, a huge amount of information is generated and consumed by millions of people in these types of networks. Currently, most popular online social networks are based on centralized servers, whom are responsible ma...

The Peer-to-Peer (P2P) technology provides support to build virtual computing system over the Internet which is dedicated for large scale computation problems. In such systems to achieve higher scalability and decentralization participating peers are classified into different groups. In P2P computing systems each peer group is responsible to carry out certain functionality of the system. Select...

Peer-to-Peer (P2P) networks are the latest addition to the universe of distributed systems. Emphasizing decentralization and selforganization the P2P networks tend to be more robust and scalable than other forms of distributed systems. Especially in the domain of file-swapping P2P networks seem to outperform other approaches largely due to the anonymity of the participants in the peer-network, ...

Link based authority analysis is an important tool for ranking resources in social networks and other graphs. Previous work have presented JP , a decentralized algorithm for computing PageRank scores. The algorithm is designed to work in distributed systems, such as peer-to-peer (P2P) networks. However, the dynamics of the P2P networks, one if its main characteristics, is currently not handled ...

P2P computing lifts taxing issues in various areas of computer science. The largely used decentralized unstructured P2P systems are ad hoc in nature and present a number of research challenges. In this paper, we provide a comprehensive theoretical survey of various state-of-the-art search and replication schemes in unstructured P2P networks for file-sharing applications. The classifications of ...
