摘要
在分析P2P技术及个人数字图书馆内涵的基础上,提出一种抑制搭便车行为的激励机制TOIM,基于非结构化P2P网络拓扑,通过邻居选择、删除、数量评测以及置换机制将信誉值较高的个人数字图书馆推到网络中心,使信誉值较低的个人数字图书馆逐渐趋于网络边缘。仿真实验结果表明该机制在一定程度上促进了PDLs之间的共建共享。
On the basis of analyzing P2P technology and the connotation of Personal Digital Libraries （ PDLs）, an incentive mechanism which is inhibiting free -riding behavior, named TOIM, is proposed. Based on unstructured P2P network topology, through neighbor selection, deletion, quality evaluation and replacement mechanism, it pushes the PDLs which have higher credibility into the center of network, drives the PDLs which have lower credibility into the edge of network. The result of the simulation experiment shows that this mechanism could promote co - construction and sharing of PDLs at a certain extent.
