摘    要:提出一种基于兴趣相似度的可信群划分策略.将全局评估转化为群内评估,既解决了评估消息集聚的问题,又区分了不同兴趣域内的评估结果,提高了系统的服务成功率.同时提出一种结合评估值波动性和一致性的权重计算方法.仿真结果表明,新模型能抵抗各类恶意节点,且比以往的模型服务成功率更高.

关 键 词:可信群  兴趣相似度  权重  波动性  一致性

Abstract:A classifying strategy for trusted groups is presented according to the interest similarity.The global trusted evaluation is transformed into the local evaluation in the trusted group,thus it addresses the centralizing problem of evaluation news and separates evaluation results among different interest groups to improve the success of serving for the system.Meanwhile,a weighted calculating method is proposed by combining the volatility with the consistency of the evaluation value.Simulation results show that the proposed model can combat all kinds of malicious nodes,and yield higher serving success rate than the previous models.
Keywords:trusted group  interest similarity  weight  volatility  consistency
