摘　　要：针对自私节点的恶意丢包行为,将节点和其邻居节点所监测的结果结合起来,计算出节点间的信任度,并以此作为路由选择的依据来促进节点间的相互合作,提出一种基于邻居合作监测的移动Adhoc网络信任模型.将信任模型应用于DSR路由协议并在NS2中进行仿真实验,结果表明该信任模型可以有效地缓解自私节点造成的影响,提高了网络的分组投递率.In order to deal with the behaviors of dropping packet by selfish nodes, a trust model using neighbor cooperation monitoring in mobile Ad hoc networks is proposed. This trust model computes the trust values with the monitoring results between nodes, and then uses the trust values to select routing. The model is applied to DSR protocol and is simulated in NS2. The experimental results show that the proposed model can effectively reduce the impact caused by selfish nodes and improve the packet delivery rate.
