Distributed optimization of media flows in peer-to-peer overlay networks

We consider the problem of rate-distortion (RD) optimized media streaming in unstructured peer-to-peer (P2P) overlay networks. We formulate the aforementioned problem as a distributed rate allocation problem. To solve the problem for all the participating ...

LSH At Large - Distributed KNN Search in High Dimensions

Karl Aberer, Sebastian Michel, Parisa Haghani

We consider K-Nearest Neighbor search for high dimensional data in large-scale structured Peer-to-Peer networks. We present an efficient mapping scheme based on p-stable Locality Sensitive Hashing to assign hash buckets to peers in a Chord-style overlay ne ...

Rumor Spreading in LiveJournal

Saket Sathe

Online social networks have gained importance in recent years. Furthermore, there is a need for designing smart applications for social networks which take into account the behaviour of dynamical processes over these networks. This requires structural know ...

Reputation Systems for Self-Organized Networks

Jean-Yves Le Boudec, Jochen Mundinger, Sonja Buchegger

Self-organized networks such as mobile ad-hoc, Internet-based peer-to-peer, wireless mesh and Fourth Generation (4G) Wireless networks depend on cooperation of nodes. Reputation systems help nodes decide with whom to cooperate and which nodes to avoid. The ...

Fuzzynet: Zero-maintenance Ringless Overlay

Karl Aberer, Anwitaman Datta, Wojciech Galuba, Sarunas Girdzijauskas

Many structured overlay networks rely on a ring invariant as a core network connectivity element. The responsibility ranges of the participating peers and navigability principles (greedy routing) heavily depend on the ring structure. For correctness guaran ...

Effective Usage of Computational Trust Models in Rational Environments

Karl Aberer

Reputation-based trust models based on statistical learning have been intensively studied for large-scale distributed systems whereas practical application of game-theoretic approaches using sanctioning are still very little understood in such settings. Th ...

Effective Usage of Computational Trust Models in Rational Environments

Karl Aberer

Reputation-based trust models using statistical learning have been intensively studied for distributed systems where peers behave maliciously. However practical applications of such models in environments with both malicious and rational behaviors are stil ...

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 ...

A Survey of Semantic Based Peer-to-Peer Systems

This paper makes a step in identifying the state of the art in semantic P2P systems. On one hand, lot of research in the P2P systems community has focused on fault-tolerance and scalability, resulting in numberous algorithms, systems such as Chord, Pastry ...
