A Point-Based Incentive Scheme for P2P Reputation Management Systems

This paper proposes an incentive scheme for P2P resource management systems which encourages the users to evaluate the “trustworthiness of evaluations” given by the other users. More concretely, in the proposed scheme, each user earns a reward from other users by evaluating their evaluations, and a user which acquires a large number of evaluations will be granted a right to access high quality services. To this end, we introduce the notion of evaluation points which mediates the “evaluation of services” and the “evaluation of evaluations.” The performance of the proposed incentive scheme is evaluated by simulation. The simulation results indicate that: 1) the proposed scheme certainly encourages the users to conduct an evaluation of evaluations, 2) it encourages users to provide high quality evaluations of the services, and 3) a rational strategy for the users is to repeat evaluation of evaluations after conducting a certain number of evaluations of services.
