摘　　要：为提升自由空间光网络通信传输时的数据可靠性,提出了考虑数据传输可靠性的自由空间光网络路由方法。分析在大气环境的通信损耗,构建可靠性模型,通过可靠性模型对比直传链路与中继链路的可靠性,并按照距离阈值选取最佳通信链路,采用绿色路由算法,以能耗作为权重,降低路由的链路选择能耗,实现光网络通信传输节能优化。经实验验证,该方法的光网络能耗小于0.16 J,最大传输数据时延小于12 s下,数据传播范围250 m,链路传输数据的可靠性高,工作节点与死亡节点分布均匀。In order to improve the data reliability of free space optical network,a routing method considering the data transmission reliability is proposed.Analyze the communication loss in the atmospheric environment,build a reli-ability model,compare the reliability of direct link and relay link through the reliability model,select the best commu-nication link according to the distance threshold,adopt the green routing algorithm,take the energy consumption as the weight,reduce the link selection energy consumption of routing,and realize the energy-saving optimization of optical network communication transmission.The experimental results show that the optical network energy consumption of this method is less than 0.16 J,the maximum transmission data delay is less than 12 s,the data transmission range is 250 m,the reliability of link transmission data is high,and the distribution of working nodes and dead nodes is uniform.
