摘　　要：针对传统方法中,采用码元帧格式扫频方法实现路由信道均衡,达到路由冲突分流控制的目的,但网络信道的扩展损失呈突变衰减时,路由冲突分流控制性能不好。提出基于时间和频率的能量密度分析的格栅状网络环式路由冲突分流控制算法。在双向链路中进行数据流的编码,采用FDMA协议进行路由冲突设计,构建网络带宽频间路由冲突信号模型,根据多目标优化理论,采用时频信号处理的方法,提取能量密度特征,实现格栅状网络环式路由冲突分流控制。仿真结果表明,该算法能有效提高路由负载的均衡度,路由冲突分流控制性能较好,提高了通信性能的稳定性。Aiming at the traditional method, using the frame format symbol sweep method to achieve routing channel equalization, to achieve the purpose of routing conflict shunt control,however, the propagation loss of the network channel was abrupt and the control performance was not good. Based on the energy density analysis of time and frequency, a grid ring routing algorithm was proposed. The data stream encoding in the two-way link, using FDMA protocol to design routing conflict, network bandwidth frequency routing conflict signal model, based on the theory of multi-objective optimization, using the method of time-frequency signal processing, extracting energy density characteristics and realize the network grid ring routing flow control. The simulation results showed that the algorithm can effectively improve the balance of routing load, the performance of the routing conflict shunt control was better, and the stability of the communication performance was improved.
