Incentive Compatible Mechanism in P2P Systems

Free-riding is that nodes only consume the resources of the contribution by other nodes, instead of sharing their resources. The problem of free-riding in P2P network is serious. Free-riding behaviors seriously limit the advantage of P2P. In this paper, the model based on the micropayment platform with an incentive mechanism is presented. Through packaging, pricing and clearing mechanisms in the model, the equal services between nodes can be achieved. Experiments show that the model can effectively solve the problem of free-riding.
