图8三类节点的全局信任度测试
法对团队恶意节点的欺骗行为进行判断.
(3)实验3.相关性信任度有效性验证.
首先,在实验2的环境下,观察一个A类节点n1和A类节点口2、C类节点f2的相关性因子,结果如图9所示.
循环次数
图9相关性因子测试
图9结果表示,随着不断的实验,节点口1与口2的相关性因子越来越高,而口1与f2的相关性因子一直处于低等水平,表明相关性因子的设计合理.
同时,实验观察口1对口2、n1对c2的相关性信任度评价,结果如图10所示.
图10相关性信任度MDHT(al,a2)与
MDHT(al,c2)测试
结果表明,由于有团队的影响,n2和f2都具有高的全局信任度,但是,由于加入了相关性因子,使得最终的MDHT(口1,a2)与MDHT(al,c2)能清楚地区分可信节点与团队恶意节点,相关性信任度具有更高的客观性.
(4)实验4.与其它模型的性能比较.
本文将MDHTrust中的相关性信任模型与EigenRep模型[1引、Jiang的模型[173、NBRTrust模型[2引、随机模型进行比较实验.实验统计在不同信任模型下所有A类节点选择从恶意节点(B类和C类)进行交易的次数在总交易次数中所占的比重(如所有A类节点总共交易了100次,其中有20次选择了B类和C类交易,则比例为20%).实验结果如图11所示.
图11不同模型选择恶意节点进行交易的比例
从图11的实验结果看,随机模型具有最差的收敛性,而MDHTrust的收敛效果较好.虽然EigenRep模型和Jiang的模型都能有效收敛,但由于这两个模型都没有引入相关性参数,使得其对实验环境中的团队恶意节点(C类节点)的协同行为反应较慢.尽管在Jiang模型中引入了对评价的信任判断来处理协同恶意行为,同时通过线性时间因子对评价进行了因式处理,但相比MDHTrust的相关性因子和非线性时间因子,其收敛速度相对较慢.NBRTrust模型因本身较为简单,只计算了成功率和相关性因子,这使得其收敛效果较差.该结果表明,相比EigenRep模
