摘要
提出一种基于兴趣群组的有效抗攻击性自组网络信任激励模型IGTrust,通过采用经济学中收益与损失概念,屏蔽了不同评价主体对同一行为评价的差异性.IGTrust将信任关系划分为三种类型,以节点获得的相对收益作为信任评估依据,结合交易信息量、折扣因子、时间维度等参数给予了各自的解决方案.仿真实验结果表明,IGTrust在抗恶意节点攻击与资源查询性能等方面均有良好性能.
An interest group based trust model（IGTrust） for ad hoc networks is presented in this paper.Using the income and costs,IGTrust masks the difference of a transaction＇s trust from different evaluating peers.Trust relationship in IGTrust which employ the relative income of a peer（or system） as its trust information is divided into three kinds and each solution is also put forward in view of transactions,discount factor and time.Subsequent experimental results show that IGTrust is robust on trust security and also low costs and failure rate when resource search happens.
