摘　　要：信息资源共享的效果取决于用户分享信息的动因和分享信息的质量.在移动互联网场景下,为了激励用户分享高质量的信息资源,设计了基于信誉度量的资源共享机制,提出了基于信誉度量的资源与用户匹配方法实现用户信息需求的精确匹配,通过用户信誉的更新方法实现用户分享动因和分享资源质量的动态评价.构建移动互联网点对点信息资源共享平台,实现基于信誉度量的资源共享机制.大规模仿真实验和基于真实平台的实验结果表明,该机制有效提高了用户的资源共享率和共享资源的质量.The performance of information resource sharing depends on users＇ sharing motivations and shared information quality. In the mobile Internet scenario,to encourage users to share high-quality resources,a reputation based resource sharing mechanism was designed,including a reputation based resource and user matching algorithm for precisely satisfying users＇ information demand and user reputation update algorithm for dynamically evaluating users＇ reputation. A point-to-point information resource sharing platform was established,and the proposed reputation based resource sharing mechanism was achieved. Extensive simulations and experiments in real scenarios demonstrate that such mechanism can improve the users＇ resource sharing ratio and shared resource quality.
