“…Aberer and Despotovic [13] suggest a mechanism for P-Grid, a peer-to-peer system that spreads negative information only. Collaboration enforcement in peer-to-peer systems has also been considered by Moreton and Twigg [14]. Carbone et al [15] introduce a formal model for trust in dynamic networks.…”

SUMMARYSelf-organised networks require some mechanism to ensure cooperation and fairness. A promising approach is the use of decentralised reputation systems. However, their vulnerability to liars has not yet been analysed 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 not differ too much from their reputation values. We simplify the original system in order to obtain a one-dimensional formulation and show that it exhibits a phase transition. In the subcritical regime, the reputation system is robust. In the supercritical regime, lying has an impact. We obtain the critical values via a mean-field approach and verify the results by explicit computation. Thus, we provide conditions for the deviation test to make the reputation system robust as well as quantitative results on what goes wrong in the supercritical regime.

Considering the fact that P2P (Peer-to-Peer) systems are self-organized and autonomous, social-control mechanism (like trust and reputation) is essential to evaluate the trustworthiness of participating peers and to combat the selfish, dishonest and malicious peer behaviors. So, naturally, we advocate that P2P systems that gradually act as an important information infrastructure should be multi-disciplinary research topic, and reflect certain features of our society. So, from economic and social perspective, this paper designs the incentive-compatible reputation feedback scheme based on well-known economic model, and characterizes the social features of trust network in terms of efficiency and cost. Specifically, our framework has two distinctive purposes: first, from high-level perspective, we argue trust system is a special kind of social network, and an accurate characterization of the structural properties of the network can be of fundamental importance to understand the dynamics of the system. Thus, inspired by the concept of weighted small-world, this paper proposes new measurements to characterize the social properties of trust system, that is, high global and local efficiency, and low cost; then, from relative low-level perspective, we argue that reputation feedback is a special kind of information, and it is not free. So, based on economic model, VCG (Vickrey-Clarke-Grove)-like reputation remuneration mechanism is proposed to stimulate rational peers not only to provide reputation feedback, but truthfully offer feedback. Furthermore, considering that trust and reputation is subjective, we classify the trust into functional trust and referral trust, and extend the referral trust to include two factors: similarity and truthfulness, which can efficiently reduce the trust inference error. The preliminary simulation results show the benefits of our proposal and the emergence of certain social properties in trust network.

“…The terms reputation and trust are being used for various concepts in the literature, also synonymously [5,6]. We define the term reputation here to mean the performance of a principal in participating in the base protocol as seen by others.…”

“…Thus, this implies that the proposed algorithm is not only improving the performance but also providing a chance to choose the optimal values of critical parameters. Equation (4) To formalize the above discussion, we can combine probabilities of transmission from (1) and (2) with the total available time per node from (3) in (5). Thus this expresses the node throughput not only by means of total available time but also by means of the total number of packets a node can transmit.…”

Abstract-This paper provides a critical analysis of the recent research wok and its impact on the overall performance of a mobile Ad hoc network. In this paper, we clarify some of the misconceptions in the understating of selfishness and missbehavior of nodes. Moreover, we propose a mathematical model that based on the time division technique to minimize the node misbehavior by avoiding unnecessary elimination of bad nodes. Our proposed approach not only improves the resource sharing but also creates a consistent trust and cooperation (CTC) environment among the mobile nodes. We believe, that the proposed mathematical model not only points out the weaknesses of the recent research work but also approximates the optimal values of the critical parameters such as throughput, transmission over head, channel capacity etc. The simulation results demonstrate the success of the proposed approach that significantly minimizes the malicious nodes and consequently maximizes the overall throughput of the Ad Hoc network than the other well known schemes.
