Asymmetric Incentives in Peer-to-Peer Systems
In most application scenarios for Peer-to-Peer systems, in order to achieve an overall acceptable system performance an incentive scheme is required that motivates users to share as much as possible of their free resources Today most peers use connections of asymmetric links, such as A-DSL or cable modems. Therefore, users have significantly more download bandwidth than their available upload b...
متن کاملAdding Incentives to Peer-to-Peer Systems
Modern peer-to-peer systems rely heavily on the willingness of users to distribute files to their peers. A selfish user can choose to download a file and consume resources without uploading in return. This form of free-riding plagues all currently deployed systems. We present a protocol for a BitTorrent-like system (i.e., in which only one file is being shared) that strongly discourages peers f...
متن کاملIncentives in Peer-to-Peer and Grid Networking
Today, most peer-to-peer networks are based on the assumption that the participating nodes are cooperative. This works if the nodes are indifferent or ignorant about the resources they offer, but limits the usability of peer-to-peer networks to very few scenarios. It specifically excludes their usage in any non-cooperative peer-to-peer environment, be it Grid networks or mobile ad-hoc networks....
متن کاملIncentives for Truthful Peer Grading
Peer grading systems work well only if users have incentives to grade truthfully. An example of nontruthful grading, that we observed in classrooms, consists in students assigning the maximum grade to all submissions. With a naive grading scheme, such as averaging the assigned grades, all students would receive the maximum grade. In this paper, we develop three grading schemes that provide ince...
متن کاملFairness, incentives and performance in peer-to-peer networks
In this paper we consider the sensitivity of the ‘service capacity’ of peer to peer (P2P) file sharing applications to demands, user cooperation, and providing incentives for cooperation through fairness guarantees. To do so we propose models for both the steady state performance and the transient characteristics of the system. Both are of interest since, from the perspective of a given file, d...
