Recommendation Retrieval in Reputation Assessment for Peer-to-Peer Systems

Recommendation Retrieval in Reputation Assessment for Peer-to-Peer Systems

Recommendation-based reputation assessment in peer-to-peer systems relies on recommendations in predicting the reputation of peers. In this paper, we discuss the effectiveness and cost metrics in the recommendation retrieval. We evaluate the following retrieval methods: flooding, recommendation tree, and the storage peer. The simulation results show that overlay network construction significant...

Examining Metrics for Peer-to-Peer Reputation Systems

As the popularity of resource-sharing through peer-to-peer networks increases, so does the threat of agents seeking to weaken the network by propagating bad information and services. This paper presents advantages and disadvantages of resource selection techniques based on peer reputation. We evaluate the effect of limited reputation information sharing on the efficiency and load distribution o...

Information Retrieval in Peer to Peer Systems

Information Retrieval in Peer-to-Peer Systems

Applying information retrieval techniques in peer-to-peer infrastructures is a demanding challenge. Peer-to-peer systems are already being used for a vast number of applications in content exchange, but mostly searching is done by simple keyword lookups. In contrast, information Retrieval techniques vastly differ from retrieval in pure data management systems. Information retrieval means that n...

Trust and Reputation in Peer-to-Peer Systems

Peer-to-peer (P2P) systems are distributed systems in which nodes act as peers, in the sense that all of them have similar roles in the network, being both providers and consumers of services. Such systems are becoming very popular in applications like file sharing. In this kind of architecture, trust and reputation are fundamental requirements for the reliability of the system. Since services ...
