By combining an unstructured protocol with a DHT-based global index, hybrid peer-to-peer (P2P) improves search efficiency in terms of query recall and response time. The major challenge in hybrid search is how to estimate the number of peers that can answer a given query. Existing approaches assume that such a number can be directly obtained by computing item popularity. In this work, we show that such an assumption is not always valid, and previous designs cannot distinguish whether items related to a query are distributed in many peers or are ....etc

Security Issues of P2P Networks

Abstract
P2P applications introduce a whole new series of security issues, security within the virtual P2P networks themselves and security with respect to the environments they ride on. P2P technology can undermine network security and can leave computing devices open to threats ranging from violations of intellectual property laws, virus ....etc

CONTENTS
1. AIMS AND OBJECTIVE: Collusive piracy is the main source of intellectual property violations within the boundary of a P2P network. Paid clients (colluders) may illegally share copyrighted content files with unpaid clients (pirates). Such online piracy has hindered the use of open P2P networks for commercial content delivery.
The main sources of illegal file sharing are peers who ignore copyright laws and collude with pirates. To solve this peer collusion problem, we propose a copyright-compliant system for leg ....etc

ABSTRACT
Peer-to-peer le-sharing networks are currently receiving much at- tention as a means of sharing and distributing information. How- ever, as recent experience shows, the anonymous, open nature of these networks offers an almost ideal environment for the spread of self-replicating inauthentic les. We describe an algorithm to decrease the number of downloads of inauthentic les in a ....etc

1. INTRODUCTION
A new and growing technique in the world of the Internet is the Peer-to-Peer architecture, usually referred to as P2P, in which each node on a network is assumed a peer for other connected nodes to have node-to-node data communication and resource sharing. As the number of Internet users is increasing and their knowledge of Internet resources is developing, a more powerful and convenient tool to communicate is in demand. The P2P technique may provide such a tool.

pFusion: A P2P Architecture for Internet-Scale Content-Based Search and Retrieval

Abstract”The emerging Peer-to-Peer (P2P) model has become a very powerful and attractive paradigm for developing Internet-scale systems for sharing resources, including files and documents. The distributed nature of these systems, where nodes are typically located across different networks and domains, inherently hinders the efficient retrieval of information. In this paper, we consider the effects of topologically aware overlay construction techniques o ....etc

Collusive piracy is the main source of intellectual property violations within the boundary of a P2P network. Paid clients (colluders) may illegally share copyrighted content files with unpaid clients (pirates). Such online piracy has hindered the use of open P2P networks for commercial content delivery. We propose a proactive content poisoning scheme to stop colluders and pirates from alleged copyright infringements in P2P file sharing. The basic idea is to detect pirates timely with identity-based signatures and time stamped tokens. The schem ....etc

Peer to Peer (P2P) Search Engine

World Wide Web (WWW) is emerging as a source of online information at a very faster rate.Itâ„¢ s content is considerably more diverse and certainly much larger than what is commonly understood. Information content in WWW is growing at a rate of 200% annually. The sheer volume of information available makes searching for specific information quite a daunting task. Search engines are efficient tools used for finding relevant information in the rapidly growing and highly dynamic web. There are quite a number ....etc

During recent years, peer-to-peer (P2P) file-sharing sys- tems have evolved in many ways to accommodate growing numbers of participating peers. In particular, new features have changed the properties of the unstructured overlay topology formed by these peers. Despite their importance, little is known about the characteristics of these topologies and their dynamics in modern file-sharing applications. This paper presents a detailed characterizat ....etc
