Promoting synergies for sustainability through peer-to-peer sharing: an analysis of drivers and barriers

Claudia Rebeca Binder Signer, Ralph Hansmann

Peer-to-peer (P2P) sharing may foster sustainability synergistically by saving resources, reducing costs and promoting satisfaction of consumer needs and social connectivity. A survey of Swiss and Swedish consumers (N = 1522) was conducted to analyze drive ...

Fair Incentivization of Bandwidth Sharing in Decentralized Storage Networks

Verónica del Carmen Estrada Galiñanes

Peer-to-peer (p2p) networks are not independent of their peers, and the network efficiency depends on peers contributing resources. Because shared resources are not free, this contribution must be rewarded. Peers across the network may share computation po ...

Moby: A Blackout-Resistant Anonymity Network for Mobile Devices

Antoine Rault, Bryan Alexander Ford, Amogh Pradeep, Hira Javaid

Internet blackouts are challenging environments for anonymity and censorship resistance. Existing popular anonymity networks (e.g., Freenet, I2P, Tor) rely on Internet connectivity to function, making them impracticable during such blackouts. In such a set ...

Wideband Cavity-Backed CubeSat Antenna in S band

Anja Skrivervik, Miroslav Veljovic

The Telemetry, Tracking and Command (TT&C) antennas are a crucial component of small satellites, as their in-orbit attitude is not always well-defined. The TT&C antenna design for a CubeSat is an even more challenging task, considering the volume restricti ...

In-Network View Synthesis for Interactive Multiview Video Systems

Pascal Frossard, Laura Toni

In multiview applications, camera views can be used as reference views to synthesize additional virtual viewpoints, allowing users to freely navigate within a 3D scene. However, bandwidth constraints may restrict the number of reference views sent to clien ...

Method to optimize the communication parameters between an access point and at least one client device

Patrick Thiran, Ruben Merz, Julien Pierre Sacha Herzen

A method to optimize the communication on a channel between an access point and at least one client device, said channel being characterized by a center frequency and a bandwidth, comprises: establishing a connection on a first channel according to a first ...

Interactive Free Viewpoint Video Streaming Using Prioritized Network Coding

Pascal Frossard, Nikolaos Thomos, Laura Toni

In free viewpoint applications, the images are cap- tured by an array of cameras that acquire a scene of interest from different perspectives. Any intermediate viewpoint not included in the camera array can be virtually synthesized by the decoder, at a qua ...

Distributed Rate Allocation With Intersession Network Coding

Pascal Frossard, Nikolaos Thomos, Eirina Bourtsoulatze

In this paper, we propose a distributed rate allocation algorithm for delay minimal data delivery in overlay networks where multiple sources compete simultaneously for the available network resources. In order to efficiently utilize the network resources, ...

Signaling and Reciprocity : Robust Decentralized Information Flows in Social, Communication, and Computer Networks

Wojciech Galuba

Complex networks exist for a number of purposes. The neural, metabolic and food networks ensure our survival, while the social, economic, transportation and communication networks allow us to prosper. Independently of the purposes and particularities of th ...

Scalable Video Dissemination with Prioritized Network Coding

Pascal Frossard, Nikolaos Thomos, Eymen Kurdoglu

In this paper, we present a pull-based dissemination protocol for efficient distribution of scalable video content in overlay peer-to-peer networks with mesh structures. The proposed protocol employs prioritized network coding, where the network coded pack ...

Fuzzynet: Ringless Routing in a Ring-like Structured Overlay

Karl Aberer, Anwitaman Datta, Sarunas Girdzijauskas, Wojciech Galuba

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 ...

Live Streaming with Gossip

Maxime Monod

Peer-to-peer (P2P) architectures have emerged as a popular paradigm to support the dynamic and scalable nature of distributed systems. This is particularly relevant today, given the tremendous increase in the intensity of information exchanged over the Int ...

Bandwidth Adaptation in Streaming Overlays

Dejan Kostic, Simon Schubert, Nedeljko Vasic

A major challenge for real-time streaming overlays is to distribute high bit-rate streams with uninterrupted playback. Hosts usually have sufficient inbound bandwidth to support streaming, but due to the prevalence of asymmetric links in broadband networks ...

Tunable Privacy for Access Controlled Data in Peer-to-Peer Systems

Karl Aberer, Zoltán Miklós

Peer-to-peer paradigm is increasingly employed for organizing distributed resources for various applications, e.g. content distribution, open storage grid etc. In open environments, even when proper access control mechanisms supervise the access to the res ...

Query-Driven Indexing for Scalable Peer-to-Peer Text Retrieval

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

In this paper, we present a query-driven indexing/retrieval strategy for efficient full text retrieval from large document collections distributed within a structured P2P network. Our indexing strategy is based on two important properties: (1) the generate ...

Self-organized fault-tolerant routing in peer-to-peer overlays

Zoran Despotovic, Karl Aberer, Wojciech Galuba

In sufficiently large heterogeneous overlays message loss and delays are likely to occur. This has a significant impact on overlay routing, especially on longer paths. The existing solutions to this problem rely on message redundancy to mask the loss and d ...

Designing peer-to-peer overlays : a small-world perspective

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 ...

Memory Organization and Data Layout for Instruction Set Extensions with Architecturally Visible Storage

Paolo Ienne, Yusuf Leblebici, Philip Brisk, Panagiotis Athanasopoulos

Present application specific embedded systems tend to choose instruction set extensions (ISEs) based on limitations imposed by the available data bandwidth to custom functional units (CFUs). Adoption of the optimal ISE for an application would, in many cas ...
