摘　　要：受到时延和丢包问题的影响,以往链路规划方法的使用效果不佳,由此,提出舰船无线通信网络链路非线性规划数学模型分析方法。描述链路非线性规划问题,应用Whittle方法进行规划参数确定,结合离散小波变换方法组合模型参数,对不同时间尺度下的网络流量进行分解;通过判定最短流量数据的传输链路,将参数代入组合模型,得到相应的舰船无线通信网络链路非线性规划数学模型;利用非线性反馈控制原理,有效补偿系统的容错现象,改善系统的时延和丢包问题。由实验结果可知,该模型最低丢包率为0.70%,最大时延为3 ms,具有良好的非线性规划效果。Due to the influence of delay and packet loss,the previous link planning methods are not effective.Therefore,a mathematical model analysis method of nonlinear programming for ship wireless communication network link is proposed.The link nonlinear programming problem is described.Whittle method is used to determine the planning parameters.Combined with discrete wavelet transform,the model parameters are combined to decompose the network traffic in different time scales;By determining the shortest traffic data transmission link and substituting the parameters into the combination model,the corresponding nonlinear programming mathematical model of ship wireless communication network link is obtained;The nonlinear feedback control principle is used to compensate the fault tolerance of the system and improve the delay and packet loss of the system.The experimental results show that the minimum packet loss rate of the model is 0.70%,and the maximum delay is 3 ms,which has a good nonlinear programming effect.
