摘　　要：激光通信网络在进行信息传输时容易受到离散变量的影响,降低信息传输质量。为此,研究离散变量影响下激光通信网络拓扑结构优化方法。生成激光通信网络初始拓扑结构,分析离散变量带来的影响。根据激光通信网络拓扑结构优化目标,建立激光通信网络的拓扑结构优化目标模型。采用多目标进化方法,剔除拓扑结构中的冗余链路,实现对激光通信网络拓扑结构的优化。实验结果表明,所提方法优化后的网络拓扑结构链路平均长度在50 cm以下,通信节点能量在48 J以上,网络生存轮数高于371轮,优化性能好,有效剔除了网络拓结构中的冗余路径。When laser communication network transmit information,it is easy to be affected by discrete variables,which reduces the quality of information transmission.Therefore,the optimization method of laser communication network topology under the influence of discrete variables is studied.The initial topological structure of laser communication network is generated,and the influence of discrete variables is analyzed.According to the optimization target of laser communication network topology,the optimization target model of laser communication network topology is established.Multi-objective evolution method is adopted to eliminate redundant links in the topological structure and optimize the topological structure of laser communication network.The experimental results show that the average link length of the optimized network topology is less than 50cm,the energy of communication nodes is more than 48J,and the number of network survival rounds is more than 371.The optimization performance is good,and the redundant paths in the network topology are effectively eliminated.
