摘　　要：为了提升多频无线网络通信质量,需要进行多频无线网络通信同步实时维护。但是采用当前方法进行无线网络通信维护时,无法提取节点的异常特征值,存在网络通信维护精度低的问题。现提出一种基于高效容错的多频无线网络通信同步实时维护方法。上述方法先利用时间相关性原理定义每个通信节点的邻域,得到节点与其邻域内节点测量值的差值,将所有的节点坐标映射为一个二维矢量,给出故障节点的判断阈值,得到故障节点的数据传输频率,并判断多频无线网络通信系统的状态,完成对多频无线网络通信同步实时维护。仿真证明,所提方法对通信系统状态判断正确率高,可以有效的提升多频无线网络通信质量。A real-time maintenance method of communication synchronization in multi-frequency wireless net- work is proposed based on efficient fault-tolerant. Firstly, principle of temporal correlation is used to define neighbor- hood of each communication node, and difference value between node and the node in its neighborhood is obtained. Then, coordinate of all nodes is mapped as a two-dimensional vector, and judging threshold of failure node is provid- ed. Moreover, frequency of data transmission of failure node is obtained, and the state of communication system of multi-frequency wireless network is judged. Finally, the real-time maintenance is completed. Simulation results show that the method has high judgment accuracy of state of communication system. It can improve communication quality of multi-frequency wireless network effectively.
