中文摘要：
基于固定网络的信任模型缺乏对网络高度动态性的考虑，不能直接应用于移动P2P网络。本文利用节点的报文转发能力，提出了一种移动P2P环境下的分布式信任模型MobTrust。该模型通过分布式存储机制，将节点转发的评价数据备份于K桶中，扩充了评价数据的存储范围。同时，鉴于移动设备有限的计算能力，设计双反馈机制提高评价数据的可靠性，然后以轻量级的方式计算信任度。仿真结果表明，MobTrust能有效降低系统开销，并拥有较高的评价数据利用率和交易成功率。
英文摘要：
Since the trust models regarding wire networks neglect the high dynamics of networks, they cannot be applied to mobile P2P networks. In this paper, a distributed trust model based on packet-forwarding, called MobTrust, is presented. Through a distributed storage scheme, such model can make the ratings data distribute in mobile P2P networks. Note that and the limitation of mobile devices, a bi-feedback scheme is designed to improve the reliability of rating data. Hereby, a lightweight method for quantifying trust value is put forward. The simulation results show that MobTrust is more advanced in system costs, and can perform much better in the usage of rating data as well as successful transaction rate.
