The dynamic scheduling method of air-space-ground integrated wireless optical communication resources based on low-orbit constellation network is studied to efficiently and accurately allocate its communication resources to ensure resource utilization and communication efficiency.In combination with Software Defined Network(SDN),an integrated air-space-ground wireless optical communication network is designed,and a low-orbit constellation network including data forwarding plane and control plane is constructed.Communication services are transmitted through the forwarding plane,and the communication resources of the integrated air-space-ground wireless optical communication network are dynamically scheduled by the control plane combined with the genetic particle swarm algorithm.The results show that the proposed method can realize dynamic scheduling of the resources of the air-space-ground integrated wireless optical communication network,with high comprehensive utilization rate of resources,low communication delay,and good scheduling effect,which ensures the improvement of overall communication quality of the network.
