An Incentive Mechanism in Mobile P2P File Sharing System Based on User Preference
Proposes an incentive mechanism based on user preference called IMBUP,which is designed to encourage user to contribute to the P2P system by sharing files and forwarding dada.IMBPC integrates virtual pricing and file transfer delay estimation and allows users to choose the most appropriate node to download file based on their preference for price and delay.Simulation shows that the system with IMBUP scheme has more nodes which have higher contribution than the system with only incentive mechanism based on virtual price.
