TLDR
This paper emphasizes that these search times can be significantly influenced by the message forward algorithm and by the topology of the community, which can be easily changed by respective, local executed algorithms.Abstract:
P2P-networks become more and more interesting not only because of the emergence of file sharing systems like Gnutella. Such decentralized systems have a lot of advantages compared to centralized client-server systems. However, information search is still a central problem in such P2P web communities, since the used complete search with message chains may cause high search response times. In this paper we emphasize that these search times can be significantly influenced by the message forward algorithm and by the topology of the community, which can be easily changed by respective, local executed algorithms. For doing so, content and traffic oriented methods were proposed. Their efficiency has been proved through a simulation and the respective results.read more

Full-text federated search in peer-to-peer networks
TL;DR: P2P networks have so far mostly used simple search techniques based on document names or controlled-vocabulary terms, and provided very limited support for full-text search of document contents.
Content-based peer-to-peer network overlay for full-text federated search
Jie Lu,Jamie Callan +1 more
TL;DR: This paper proposes a content-based P2P network overlay for full-text federated search over heterogeneous, open-domain contents and local algorithms are developed to dynamically construct a network overlay withcontent-based locality and content- based small-world properties.

An Efficient Adaptive Evolvement Protocol for Peer-to-Peer Topologies
Zhang Qian,Zhang Xia,Liu Ji-ren +2 more
TL;DR: A peer-level protocol for forming adaptive topologies for unstructured P2P networks is proposed, which can restrain the vicious action of peers effectively, and also has the incentive capacity, which encourages peers to provide more authentic services in order to get more return on services.

Collective dynamics of small-world networks
TL;DR: Simple models of networks that can be tuned through this middle ground: regular networks ‘rewired’ to introduce increasing amounts of disorder are explored, finding that these systems can be highly clustered, like regular lattices, yet have small characteristic path lengths, like random graphs.

Freenet: a distributed anonymous information storage and retrieval system
TL;DR: Freenet as discussed by the authors is an adaptive peer-to-peer network application that permits the publication, replication, and retrieval of data while protecting the anonymity of both authors and readers, but it does not provide any centralized location index.

Building low-diameter P2P networks
TL;DR: The authors propose a simple scheme for participants to build P2P networks in a distributed fashion, and prove that it results in connected networks of constant degree and logarithmic diameter with no global knowledge of all the nodes in the network.

Peer-to-peer music-sharing with profit but without copy protection
TL;DR: A friendly peer-to-peer music-sharing system (the potato system) is described, which enables unknown authors to distribute their music to many new potential customers.
