At issue for any organization is the illicit dissemination of sensitive information using file sharing applications within a network, and tracking terrorist cells or criminal organizations that are covertly communicating using Voice over IP (VoIP) applications. This paper presents a field programmable gate array (FPGA)-based embedded software tool designed to process file transfers using the Bi...

Content distribution via the Internet is becoming increasingly popular. To be cost-effective, commercial content providers are considering the use of peer-to-peer (P2P) protocols such as BitTorrent to save on bandwidth costs and to handle peak demands. However, when an online content provider uses a P2P protocol, it faces a crucial issue: how to incentivize its clients to upload to their peers....

BitTorrent is a recent, yet successful peer-to-peer protocol focused on efficient content delivery. To gain a better understanding of the key algorithms of the protocol, we have instrumented a client and run experiments on a large number of real torrents. Our experimental evaluation is peer oriented, instead of tracker oriented, which allows us to get detailed information on all exchanged messa...

Among all peer-to-peer (P2P) systems, BitTorrent seems to be the most prevalent one. This success has drawn a lot of research interest on the system. In particular, there have been many lines of research studying it’s scalability, performance, efficiency and fairness. However, despite the large body of work, there has been no attempt to mathematically model, in a heterogeneous (and hence realis...

Peer-to-peer file-sharing systems offer high transfer speed at remarkably low data ownership cost. In many cases, the transfer speed can be increased if the users possess timely and accurate information over the location of other users. Furthermore, robustness and fault tolerance, issues of intense research investigation, are inextricably linked with the location and activity of the network use...

Recent research efforts have shown that the popular Bit-Torrent protocol does not provide fair resource reciprocation and allows free-riding. In this paper, we propose a novel foresighted resource reciprocation mechanism that replaces the peer selection mechanism with a reinforcement learning mechanism that adopts a foresighted resource reciprocation policy. We model the peer interactions in th...

This article covers a nouveau idea of way to collect and handle geophysical data with peer-to-peer network in near real-time. The text brief introduction the cause, technology, particular case collecting from Global Navigation Satellite System (GNSS) stations. We describe proof-of-concept implementation that has been tested. test was conducted an experimental GNSS station aggregation facility. ...

BitTorrent, one of the most widespread file-sharing P2P applications, recently introduced LEDBAT, a novel congestion control protocol aiming at (i) limiting the additional delay due to queuing, to reduce interference with the rest of user traffic (e.g., Web, VoIP and gaming) sharing the same access bottleneck, and (ii) efficiently using the available link capacity, to provide users with good Bi...
