摘要(Abstract)：

采用空-天-地协同的立体通信架构可满足电力物联网广覆盖、大连接的通信需求，但多层异构的通信网络存在结构复杂、节点分散、运维困难等问题。基于SDN（软件定义网络）控制逻辑集中的理念，提出了基于协同编排系统的电力物联网立体异构通信网络协同控制方案。开展了协同编排系统的设计需求分析并完成其功能设计。针对协同编排系统的核心功能需求，提出了改进的基于Q学习的流量调度方法。仿真结果表明，所提方法可提升异构通信网络的流量吞吐能力和负载均衡能力。
The space-air-ground integrated stereo communication networks can meet the communication requirements of wide coverage and massive connectivity of Power IoT(Internet of things). However, the multi-layer heterogeneous communication networks are characterized by complex structure, decentralized nodes, and difficult operation and maintenance. Based on the concept of centralized control logic of SDN(software-defined networking), a collaborative control scheme for stereo-heterogeneous communication networks in power IoT based on the collaborative orchestration system is proposed. The design requirements analysis of the collaborative orchestration system is carried out, and its functional design is completed. Given the core functional requirements of the system, an improved traffic scheduling method based on Q-learning is proposed. Simulation results show that the proposed method can improve the traffic throughput capacity and load balancing capacity of the heterogeneous communication networks.
