Unlike some previous researches, we now focus on deploying a reputation system in a large deployed peer-to-peer file sharing network; Maze. There are several potential problems in mapping EigenTrust to our system and we propose two methods to improve it. First, we introduce a location-aware pre-trusted peers’ choice algorithm to ensure the fairness. Then we reduce the impact of colluders by prompting trust relationships among peers in the social network. This improved reputation system has been proven to successfully imply the peers’ contributions, while at the same time, action against the colluders.

By sampling messages on the Gnutella network over a 24-hour period, we established that 70% of Gnutella users share no files, and 90% of the users answer no queries. Furthermore, we found out that free riding is distributed evenly between domains, so that no one group contributes significantly more than others, and that peers that volunteer to share files are not necessarily those who have ...

It has been proved that the use of collaboration in such systems improves its performance, but what is not known is how this collaboration is done and what is more important, how it has to be done in order to optimise the information exchange. The collaborative relationships in recommender systems can be represented as a social network. In this paper we propose several measures to analyse collaboration ...
