Abstract
Traditional networks can no longer provide better communication services. Unlike most existing work that only focuses on single-layer satellite networks and unmanned aerial networks, or star-ground fusion networks, this paper proposes an SDN-based space-air-ground integration network architecture, which has the advantages of wide coverage, high throughput and strong robustness, can provide reliable and high-speed wireless access services. This article introduces the SDN controller into space-air-ground integration network, which can improve the flexibility and programmability of network management. This article mainly studies the space-air-ground integrated architecture and the dynamic deployment of controllers on the UAV, and the next step is to study the deployment of controllers in the global scope of the space-air-ground integrated network.
