CoShare: A Cost-effective Data Sharing System for Data Center Networks

Karl Aberer, Rameez Rahman, Hao Zhuang, Imen Filali

Numerous research groups and other organizations collect data from popular data sources such as online social networks. This leads to the problem of data islands, wherein all this data is isolated and lying idly, without any use to the community at large. ...

Distributed throughput optimization over P2P mesh networks using diffusion adaptation

Ali H. Sayed

This work develops a decentralized adaptive strategy for throughput maximization over peer-to-peer (P2P) networks. The adaptive strategy can cope with changing network topologies, is robust to network disruptions, and does not rely on central processors. T ...

Designing peer-to-peer overlays

Sarunas Girdzijauskas

The Small-World phenomenon, well known under the phrase "six degrees of separation", has been for a long time under the spotlight of investigation. The fact that our social network is closely-knitted and that any two people are linked by a short chain of a ...

Storing and Indexing Spatial Data in P2P Systems

The peer-to-peer (P2P) paradigm has become very popular for storing and sharing information in a totally decentralized manner. At first, research focused on P2P systems that host 1D data. Nowadays, the need for P2P applications with multidimensional data h ...

Delay-based overlay construction in P2P video broadcast

Pascal Frossard

We consider streaming video content over an overlay network of peer nodes. Each of the nodes employs a mesh-pull mechanism to organize the download of data units from its neighbours. We propose a novel algorithm for constructing the distribution overlay, w ...

Game Theory Video Streaming

Mahdad Hosseini Kamal

We consider the problem of peer selection for multimedia trans- mission over a peer-to-peer (P2P) network to find a strategy model for peer selection for each lost packet. Our problem consists of two parts one related to the P2P network that is a peer sele ...

Sharing of probabilistically correlated data in peer-to-peer networks

Roman Schmidt

The impact of Peer-to-Peer (P2P) networks on the Internet landscape is undisputed. It has led to a series of new applications, e.g., as part of the so-called Web 2.0. The shift from the classical client-server based paradigm of the Internet, with a clear d ...

AlvisP2P: Scalable Peer-to-Peer Text Retrieval in a Structured P2P Network

Karl Aberer, Martin Rajman, Vinh Toan Luu, Ivana Podnar, Fabius Klemm, Gleb Skobeltsyn

In this paper we present the AlvisP2P IR engine, which enables efficient retrieval with multi-keyword queries from a global document collection available in a P2P network. In such a network, each peer publishes its local index and invests a part of its loc ...

Message Passing in Semantic Peer-to-Peer Overlay Networks

Karl Aberer, Philippe Cudré-Mauroux

Peer-to-Peer (P2P) systems rely on machine-to-machine ad-hoc communications to offer services to a community. Contrary to the classical client-server architecture, P2P systems consider all peers, i.e., all nodes participating in the network, as being equal ...

Bottleneck Discovery and Overlay Management in Network Coded Peer-to-Peer Systems

Christina Fragouli, Suhas Diggavi

The performance of peer-to-peer (P2P) networks depends critically on the good connectivity of the overlay topology. In this paper we study P2P networks for content distribution (such as Avalanche) that use randomized network coding techniques. The basic id ...
