Reputation-Based Investment Helps to Optimize Group Behaviors in Spatial Lattice Networks
Encouraging cooperation among selfish individuals is crucial in many real-world systems, where individuals' collective behaviors can be analyzed using evolutionary public goods game. Along this line, extensive studies have shown that reputation is an effective mechanism to investigate the evolution of cooperation. In most existing studies, participating individuals in a public goods game are as...
متن کاملAn Adaptive Group-Based Reputation System in Peer-to-Peer Networks
As more and more P2P applications being popular in Internet, one of important problem to be solved is inspiring users to cooperate each other actively and honestly, the reputation mechanism which is a hot spot for P2P research has been proposed to conquer it. Because of the characters of virtuality and anonymous in the network, it is very easy for users with bad reputations to reenter the syste...
متن کاملGroupRep: A Robust Group-based Reputation System for Peer-to-Peer Networks
Reputation systems, which allow peers to collaborate on estimating the trustworthiness of other peers, are considered as one of the promising directions against malicious behaviors in large scale Peer-to-Peer networks. However, a weakly designed reputation system is vulnerable to attacks such as unfair rating and collusion. This paper presents GroupRep a novel group-based reputation system for ...
متن کاملSpatial Resolution Enhancement in a 2D Photonic Crystal Based on Complex Square Lattice
We study the focusing properties of a two dimensional complex square-lattice photonic crystal (PC) comprising air holes immersed in Ge medium. The finite difference time domain (FDTD) method is utilized to calculate the dispersion band diagram and to simulate the image formation incorporating the perfectly matched layer (PML) boundary condition. In contrast to the common square PCs with the sam...
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...
