Abstract: 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.

Key words: resource sharing, reputation evaluation, sharing motivation, shared resource quality
