Peer-to-peer(P2P) overlay networks provide robust, scalable file sharing services. The hop distance between two virtual nodes in P2P overlay networks is irrelevant to the real distance between two nodes. Therefore, many lookup operations may be executed, without considering the real distance, even though a node wants to find a file object located in another node within the same subnet. To overc...

This paper proposes an abstract and generic topological model that captures the essence of P2P architecture. Such model should in return facilitate the exploitation of the new design space for more novel P2P systems. The paper also proposes a variant of the cube-connected cycles as a P2P overlay network that achieves O(log N) path length with O(1) neighbors. The simulation result has shown that...

Semantic Web, Web services and Peer-to-Peer technology constitute three relevant topics from which technology for knowledge sharing can benefit. The advantages ranging from the convergence of Semantic Web, Web services and Peer-to-Peer technology into the emerging Semantic P2P services have just been outlined. In this document we give an overview of the recent approaches in literature on semant...

We observe that P2P traffic has peculiar characteristics as opposed to the other type of traffic such as web browsing and file transfer. Since they exploit swarm effect — a multitude of end points downloading the same content piece by piece nearly at the same time, thus, increasing the effectiveness of caching — the same pieces of data end up traversing the network over and over again within mo...

P2P-based applications like file-sharing or distributed storage benefit from the scalability and performance of completely decentralized P2P infrastructures. However, existing P2P infrastructures like Chord or Pastry are vulnerable against selfish and malicious behavior and provide currently little support for commercial applications. There is a need for reliable mechanisms that enable the comm...

In order to guarantee both the efficiency and robustness in the Peer-to-Peer (P2P) network, the paper designs a novel Super-node Overlay Based on Information Exchange called SOBIE. Differing from current structured and unstructured, or meshed and tree-like P2P overlay, the SOBIE is a whole new structure to improve the efficiency of searching in the P2P network. The main contributions are 1) to ...

Grid computing is a service for sharing computer resources and data storage capacity over the internet. As resource requirements of recent applications increased greatly, grid systems have gained importance in the last decade. Resource discovery is the essential job in Grid computing which provides searching and identifying necessary resources for given processes. There are various Resource Dis...

Peer-to-peer is a popular distributed overlay network due to its easy deployable property. Mobile computing and communications are improving day by day. With this advancement in technologies, mobile p2p has revealed its attractions. But resource constraints such as limited bandwidth, power and memory along with nodes mobility make it challenging to build a scalable and a robust mobile p2p netwo...

Distributed applications deployed over the Internet, such as in grids, clouds, or P2P networks, crucially depend on the speed of their Internet connections. A common solution is to exploit underlying network parallelism via multipath routing within an application-level overlay network. Accurately selecting appropriate relay hosts within an overlay, however, remains a challenging problem, freque...

Peer-to-peer systems have emerged as a significant social and technical phenomenon, and they are likely to gain popularity as low-cost individual computing and storage resources become more widely available and network connectivity increases. Unlike traditional distributed systems, P2P networks aggregate large numbers of computers that join and leave the network frequently and that might not ha...
