摘要
分析了前人在资源发现中所采用方法的优缺点,提出了一种基于声望的结合不同上下文节点信任度的评估更新方案,用于指导节点选择信任度高的节点交易,从而提高了网络的安全性,且在路径选取中充分考虑消息的转发与反馈机制中的总消耗时,以保证选出的路径最佳,同时利用基于信任的节点链接更新新方法,进行拓扑更新,以避免高可信节点的拥塞.通过仿真实验的分析验证了该方法的有效性.
After analyzing advantages and disadvantages of previous resource-searching methods,the paper suggests an assessment updating scheme on the basis of reputation combining with context notes＇ trust-rate,which is utilized to direct the transaction between notes with relative higher trust-rate.Therefore it can improve the cyber-security.It can also take full account of the total cost at message forward and feedback during route choosing so as to ensure optimized one.Meanwhile the new method based on notes linking updating can refresh topology in order to keep trustworthy notes from congestion.Analysis on emulational experiments proves that the new method is effective.
