TLDR
These studies demonstrate that proposed policies lead to the dynamic formation of coalitions (cooperation) among peers, which mutually profit by the exchange of their services, without pre-existing knowledge of one another's capabilities and values of services.Abstract:
In this paper we propose fully distributed trust-based policies for p2p systems to regulate the exchange of different type of services and discourage misbehaviour. In a system of peers with different service valuations and capabilities, the resource allocation and server selection policies are based on local reputation vectors, whose elements are the reputations of the peers in providing each service of the system. Our studies demonstrate that proposed policies lead to the dynamic formation of coalitions (cooperation) among peers, which mutually profit by the exchange of their services, without pre-existing knowledge of one another's capabilities and values of services. In this way utilities of all peers progressively increase. Only misbehaving (non contributive) peers do not benefit by such a system, as proposed policies efficiently recognize and block misbehaviour.read more

TL;DR: It is argued that the design of communities suitable for this environment will encourage users to participate, enable trustworthy network creation, and provide a social layer, which can be exploited in order to design cross-layer incentive mechanisms that will further encourage Users to share their resources and cooperate at lower layers.

A multi-state reliability evaluation model for P2P networks
Hehong Fan,Xiaohan Sun +1 more
TL;DR: A new time-evolving state-transition Monte Carlo (TEST-MC) simulation model is presented for the reliability analysis of P2P networks in multiple states and shows that the model is not only valid for estimating the traditional binary-state network reliability parameters, but also adequate for acquiring the parameters in a series of non-perfect operational states.
Reputation-assisted Utility Maximization Algorithms for Peer-to-Peer Networks
TL;DR: In this article, a reputation-based mech-anism is proposed for peer-to-peer networks, where each peer allocates a portion of its link bandwidth to its own downloads, acting as client, and allocates the remaining bandwidth for serving requests made to it by other peers.

Capacity and load-aware service discovery with service selection in peer-to-peer grids
TL;DR: A capacity and load-aware service selection (CLSS) and peer cache-based service discovery (PCSD) algorithms to maximize profit with minimum resource consumption in P2P grids are proposed.

The Tragedy of the Commons
TL;DR: The tragedy of the commons as a food basket is averted by private property, or something formally like it as mentioned in this paper, which is why the commons, if justifiable at all, is justifiable only under conditions of low-population density.

Free riding on Gnutella revisited: the bell tolls?
TL;DR: A new analysis of free riding on the Gnutella network updates data from 2000 and points to an increasing downgrade in the network's overall performance and the emergence of a "metatragedy of the commons".

Limited reputation sharing in P2P systems
TL;DR: It is shown that limited reputation sharing can reduce the number of failed transactions by a factor of 20 and the efficiency and load distribution of a peer-to-peer system is evaluated.
Resource Allocation in Federated Distributed Computing Infrastructures
TL;DR: It is argued that given the appropriate mechanisms, end-users can cooperate to arrive at an optimal resource allocation in spite of excess demand, and the design and early implementation of Bellagio, a distributed resource discov-based infrastructures is presented.
