Reputation Systems for Self-Organized Networks: Lessons Learned
Self-organized networks such as mobile ad-hoc, Internet-based peer-to-peer, wireless mesh and Fourth Generation (4G) Wireless networks depend on cooperation of nodes. Reputation systems help nodes decide with whom to cooperate and which nodes to avoid. They have been studied and applied almost separately in diverse disciplines such as economics, computer science and social science, resulting in...
متن کاملAnalysis of a Robust Reputation System for Self-Organized Networks Analysis of Reputation System
Self-organized networks require some mechanism to ensure cooperation and fairness. A promising approach is the use of decentralized reputation systems. However, their vulnerability to liars has not yet been analyzed in detail. In this paper, we provide a first step to the robustness analysis of a reputation system based on a deviation test. Users accept second hand information only if this does...
متن کاملReputation Systems for Anonymous Networks
We present a reputation scheme for a pseudonymous peer-to-peer (P2P) system in an anonymous network. Misbehavior is one of the biggest problems in pseudonymous P2P systems, where there is little incentive for proper behavior. In our scheme, using ecash for reputation points, the reputation of each user is closely related to his real identity rather than to his current pseudonym. Thus, our schem...
متن کاملA collusion mitigation scheme for reputation systems
Reputation management systems are in wide-spread use to regulate collaborations in cooperative systems. Collusion is one of the most destructive malicious behaviors in which colluders seek to affect a reputation management system in an unfair manner. Many reputation systems are vulnerable to collusion, and some model-specific mitigation methods are proposed to combat collusion. Detection of col...
متن کاملService Provisioning Framework for Self-Organized Networks
Mobile ad hoc networking, as a typical example of self organized networks, is an emerging and promising communication paradigm. Not only the variety of devices but also the diversity of services is continuously increasing. Such services must be provisioned in a flexible and distributed way without central infrastructure. Thus, service deployment and management for such mobile devices are extrem...
