Adding 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 کاملAsymmetric 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 کاملUsing Incentives for Heterogeneous peer-to-peer Network
Typically in a peer-to-peer network, nodes are required to route packets for each other. This entails to a problem of “free-loaders,” nodes that use the network but refuse to route other nodes’ packets. In this paper we presented designing incentives to discourage free-loading.
متن کاملDesigning Incentives for Peer-to-Peer Routing (Technical Report)
In a peer-to-peer network, each node is typically required to route packets on behalf of other nodes. We study the problem of designing incentives to ensure that nodes carry out this responsibility. We model the interactions between nodes as a “random matching game,” and describe a simple reputation system that can provide incentives for good behavior. Using simulations, we investigate the robu...
متن کاملIncentives for Cooperation in Peer-to-Peer Networks
To model this problem, we use the Evolutionary Prisoner’s Dilemma (EPD) [3] to capture the tension between individual and social utility. In the situations that EPD characterizes, cooperation requires repetition and reputation. Both techniques increase familiarity between entities (either directly or indirectly), thereby reducing the probability of interactions with strangers and consequently e...
