Abstract

One of the underlying assumptions on the design of peer-to-peer (P2P) network is that each peer trusts each other for forwarding transit messages. However, with the growth of P2P application, especially in business model, some peers may behave as selfish, irrational nodes due to conflict of interest or for conservation bandwidth. In our model, the P2P network is considered as a virtual market-place where peers can find, provide, and use services. Since peers are owned and operated by different entities, they do not necessarily share the same goals, but rather, to serve their own interests. In this paper, incentive mechanism to motivate peers to forward messages is proposed. We have implemented the monetary as an incentive mechanism, in which peers can setup their cost to charge for transiting a message. However, with only monetary incentive, peers may misbehave. Therefore, the decentralized reputation has been implemented with monetary mechanism. This will allow an application with dramatically improved utility, co-operate among peers and hence enable whole new domains of use.
