Ontology-based peer exchange network(OPEN)

Hui Dong, Zhimin Wang, Robert A. Morris, Jun Huang
2007 2007 International Symposium on Collaborative Technologies and Systems  
Peer-to-peer systems represent a widely accepted approach to sharing massive data and services among large, diverse and varying sets of nodes in the network.  ...  In this paper, we introduce an overlay network which constructs the logical network topologies using a global ontology and peer ontological characteristics.  ...  In order to make OPEN more resilient to node failure, we use a virtual ring concept for constructing every node in the overlay network.  ...

PIPPON: A Physical Infrastructure-aware Peer-to-Peer Overlay Network

Doan Hoang, Hanh Le, Andrew Simmonds
2005 TENCON 2005 - 2005 IEEE Region 10 Conference  
At the overlay network layer, the paper proposes a simple but effective Geo-LPM/Geo-Partitioning scheme for constructing overlay that mirrors the physical Internet.  ...  The scalability and efficiency of P2P systems are determined largely by two factors: the degree of matching between the P2P overlay and its underlying physical network, and the efficiency of the P2P application  ...  These features allow P2P networks to support several important classes of distributed systems including large-scale resources discovery and sharing systems, platforms for supporting collaborative work,  ...

SOON: A Scalable Self-organized Overlay Network for Distributed Information Retrieval [chapter]

Juan Li, Son Vuong
2008 Lecture Notes in Computer Science  
For this purpose, we have designed an algorithm to extract a node's ontology summary and use that summary to compute the semantic similarity between nodes.  ...  Locating desirable resources and information from a large-scale distributed system such as P2P system and grid is a very important issue.  ...  Our objective is to make the system's dynamic topology match the semantic clustering of peers, i.e., there is a high degree of semantic similarity between peers within the clustered community; this would  ...

Distributed Semantic Overlay Networks [chapter]

Christos Doulkeridis, Akrivi Vlachou, Kjetil Nørvåg, Michalis Vazirgiannis
2009 Handbook of Peer-to-Peer Networking  
The main objective is to discover peers with similar content and then form thematically focused peer groups.  ...  Semantic Overlay Networks (SONs) have been recently proposed as a way to organize content in peer-to-peer (P2P) networks.  ...  Towards this goal, each peer uses part of its resources in order to build the necessary infrastructure for supporting web search.  ...

Peer-to-peer management of XML data

Georgia Koloniari, Evaggelia Pitoura
2005 SIGMOD record  
Peer-to-peer (p2p) systems are attracting increasing attention as an efficient means of sharing data among large, diverse and dynamic sets of users.  ...  The widespread use of XML as a standard for representing and exchanging data in the Internet suggests using XML for describing data shared in a p2p system.  ...  For example, peer N 3 is connected to both When compared to distributed clustering, the autonomy of the peers makes the application of distributed clustering in a p2p context challenging.  ...

DESENT: decentralized and distributed semantic overlay generation in P2P networks

C. Doulkeridis, K. Norvag, M. Vazirgiannis
2007 IEEE Journal on Selected Areas in Communications  
The lack of global content/topology knowledge in a P2P system is the main feature that makes SON generation challenging.  ...  The main contribution of this paper is an unsupervised method for decentralized and distributed generation of SONs (DESENT) in such a context.  ...  An approach to improve on some of the problems of Gnutella-like systems, is to use a super-peer architecture.  ...

Scalable Semantic Overlay Generation for P2P-Based Digital Libraries [chapter]

Christos Doulkeridis, Kjetil Nørvåg, Michalis Vazirgiannis
2006 Lecture Notes in Computer Science  
However, the lack of global content/topology knowledge in an unstructured P2P system demands unsupervised methods for content organization and necessitates efficient and high quality search mechanisms.  ...  Peer-to-peer (P2P) networks emerge as a promising solution to delve with these challenges.  ...  The authors would like to thank George Tsatsaronis and Semi Koen for their help in preparing the feature extraction and clustering modules.  ...

Ontology-Based Clustering and Routing in Peer-to-Peer Networks

Juan Li, Son Vuong
2005 Sixth International Conference on Parallel and Distributed Computing Applications and Technologies (PDCAT'05)  
The system exploits the semantic property of the content in the network to cluster nodes sharing similar interest together to improve the query and searching performance.  ...  Specifically, a distributed hash table (DHT) based overlay is constructed to assist peers organizing into communities. Those peers in the same community form a Gnutella-like unstructured overlay.  ...  Community construction After the clustering policies have been determined, the system can cluster peers according to it and create peer communities.  ...

Local Semantic Indexing for Resource Discovery on Overlay Network Using Mobile Agents

M. Singh, X. Cheng, R. Belavkin
2013 International Journal of Computational Intelligence Systems  
One of the most crucial problems in a peer-to-peer system is locating of resources that are shared by various nodes.  ...  Results show reduction in search load and traffic due to communication, and increase in locating of resources defined by multiple keys using mobile agent that are logically similar to user query.  ...  The peer-to-peer (P2P) systems offer solution for resource discovery by making the task of hosting distributed. However, it suffers from inefficiency to locate hosted resources.  ...
