摘　　要：针对多人同时通讯且外界干扰因素较多,电子通讯过程中容易产生信号不稳定的问题,提出云信任驱动的物联网电子通讯稳定性优化方法。将云信任机制作为各物联网电子通讯服务之间的动态演化信任关系,进行显性和隐性的不确定性转换,计算数据通信网络性能的目标函数,确认控制策略;将通信中网络节点的定位信息加入到通信数据包中,得到网络中最稳定的电子通信路径,构成网络拓扑结构;采用克拉索夫斯基法,并将通讯网络的节点工作状态划分为拥挤状态以及正常状态,计算出两者概率,判定转换平衡的范围,以此实现网络拓扑稳定性的优化。仿真结果证明,所提方法可以提高物联网电子通讯精度,且较少地受到外界干扰因素的影响,通讯传输速率较快。This paper proposes a cloud trust driven optimization method for the stability of Internet of things electronic communication for improving the stability of the electronic communication process.Cloud trust mechanism was regarded as the dynamic evolutionary trust relationship among the Internet of things electronic communication services to transform the explicit and implicit uncertainty.The target function of data communication network performance was calculated to confirm the control strategy.The location information of network nodes was introduced into the communication packet to get the most stable electronic communication path in the network, thus forming the topology of the network.Based on the Krasovsky method, the node working state of the communication network was divided into congestion state and normal state.The probability of both can be determined to judge the range of conversion balance, and finally optimized the topological stability of the network.Simulation results show that the method has high communication speed and high accuracy of Internet of things electronic communication.
