FairTorrent: A Deficit-Based Distributed Algorithm to Ensure Fairness in Peer-to-Peer Systems
2012
IEEE/ACM Transactions on Networking
Preserved Fulltext
We present FairTorrent, a new deficit-based distributed algorithm that accurately rewards peers in accordance with their contribution. ...
A FairTorrent peer simply uploads the next data block to a peer to whom it owes the most data as measured by a deficit counter. ...
We present FairTorrent, a new deficit-based distributed P2P algorithm that solves the problem of fair bandwidth exchange in the presence of free-riders and strategic peers. ...

Peer-to-peer (P2P) sharing systems use incentives for resource exchange to encourage cooperation and ensure fairness. ...
In bilateral strategies, such as BitTorrent Tit-for-Tat or deficit-based FairTorrent, individual decisions of peers utilize direct observations. It may result in low performance and unfair treatment. ...
Exchange in a BT-like system is based on bilateral incentives [3] : file downloading is possible in return for uploading to the same peer. ...

In this paper, we propose a simple, distributed, but highly efficient fairness-enforcing incentive mechanism for cooperative computing. ...
In T-Chain, symmetric key cryptography provides the basis for a lightweight, almost-fair exchange protocol, which is coupled with a pay-it-forward mechanism. ...
FairTorrent [8] uses a deficit-based distributed algorithm to achieve strong fairness, but its immunity to whitewashing and the Sybil attack is questionable in that it still uploads unencrypted blocks ...

In this light, there is a need to understand the impact of the utilization of available bandwidth on the performance of peer-assisted file distribution systems. ...
Given the growing popularity of peer-to-peer file distribution in commercial applications, it is important to understand the challenges of using p2p file-sharing protocols for file distribution, and how ...
the popular BT algorithm for file distribution. ...

Global peer ranking is one such mechanism. In this mechanism, peers are ranked based on a metric called contribution index. ...
Fairness in the terms of upload to download ratio in each peer can be achieved by this method. However, calculation of contribution index is not trivial. ...
It is a deficit based distributed algorithm in which a peer uploads the next data block to the peer, whom it owes the most data as measured by a deficit counter. ...
