Trust Estimation and Aggregation in Peer-to-Peer Network Using Differential Gossip Algorithm
In peer-to-peer networks, free riding is a major problem. Reputation management systems can be used to overcome this problem. Reputation estimation methods generally do not considers the uncertainties in the inputs. We propose a reputation estimation method using BLUE (Best Linear Unbiased estimator) estimator that consider uncertainties in the input variables. Reputation aggregation in peer to...
متن کاملGossip-Based Reputation Management for Unstructured Peer-to-Peer Networks*
To build an efficient reputation system for peer-to-peer (P2P) networks, we need fast mechanisms to aggregate peer evaluations and to disseminate updated scores to a large number of peer nodes. Unfortunately, unstructured P2P networks are short of secure hashing and fast lookup mechanisms as in structured P2P systems like the DHT-based Chord. In light of this shortcoming, we propose a gossiping...
متن کاملGenius: Peer-to-Peer Location-Aware Gossip Using Network Coordinates
The gossip mechanism could support reliable and scalable communication in large-scale settings. In large-scale peer-to-peer environment, however, each node could only have partial knowledge of the group membership. More seriously, because the node has no global knowledge about the underlying topology, gossip mechanism incurs much unnecessary network overhead on the Internet. In this paper, we p...
متن کاملGGRA: a grouped gossip-based reputation aggregation algorithm
An important issue in P2P networks is the existence of malicious nodes that decreases the performance of such networks. Reputation system in which nodes are ranked based on their behavior, is one of the proposed solutions to detect and isolate malicious (low ranked) nodes. Gossip Trust is an interesting previously proposed algorithm for reputation aggregation in P2P networks based on t...
متن کاملGossip in a Smartphone Peer-to-Peer Network
In this paper, we study the fundamental problem of gossip in the mobile telephone model: a recently introduced variation of the classical telephone model modified to better describe the local peer-to-peer communication services implemented in many popular smartphone operating systems. In more detail, the mobile telephone model differs from the classical telephone model in three ways: (1) each d...
