移动P2P文件共享系统中基于用户偏好的激励机制

提出一种基于用户偏好的激励机制,鼓励用户通过提供共享文件和转发操作为系统做出贡献。IMBPC结合了虚拟价格机制和预期文件传输延时,基于用户对价格和延时的偏好度来选择最合适的节点进行文件下载。通过设置模拟实同仅通过虚拟价格机制来激励用户做出贡献的策略进行比较,显示应用IMBPC策略的系统,节点的贡献积极性明显增加。

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.
