FairTorrent: A Deficit-Based Distributed Algorithm to Ensure Fairness in Peer-to-Peer Systems

Alex Sherman, Jason Nieh, Clifford Stein
2012 IEEE/ACM Transactions on Networking  
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.  ...

Cyclic ranking in single-resource peer-to-peer exchange

Andrei Gurtov, Joakim Koskela, Dmitry Korzun
2017 Peer-to-Peer Networking and Applications  
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.  ...

T-Chain: A General Incentive Scheme for Cooperative Computing

Kyuyong Shin, Carlee Joe-Wong, Sangtae Ha, Yung Yi, Injong Rhee, Douglas Reeves
2015 2015 IEEE 35th International Conference on Distributed Computing Systems  
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  ...

Modeling Flash Crowd Performance in Peer-to-Peer File Distribution

Cristina Carbunaru, Yong Meng Teo, Ben Leong, Tracey Ho
2014 IEEE Transactions on Parallel and Distributed Systems  
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.  ...

Simplified Biased Contribution Index (SBCI): A Mechanism to Make P2P Network Fair and Efficient for Resource Sharing [article]

Sateesh Kumar Awasthi, Yatindra Nath Singh
2017 arXiv   pre-print
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.  ...
