摘要
针对P2P系统文件共享中的大量搭便车现象,提出一种基于贡献值的新型激励机制,该机制根据节点的贡献值进行资源分配,贡献值越大的节点越能获得高的服务质量和优先级。仿真实验表明,基于贡献值的资源分配算法能有效地实现P2P系统中资源分配的公平性和效率,鼓励贡献节点,同时抑制搭便车现象。
To solve ＂free-rider＂ problems in peer-to-peer system,this paper presents a novel incentive mechanism base on the contribution of node.The incentive mechanism allocates resources base on the contribution of node.The greater contribution value of the node can obtain the higher quality of service and priority.The simulations result shows that the algorithm of resources allocate base on the contribution of node can effective achieve the fairness and efficiency of resources allocate in the P2P system,attain the purpose of encouraging the contribution node and suppressing the phenomenon of free rider.
