Query: Optimizing Space-Air-Ground Integrated Networks by Artificial
  Intelligence   It is widely acknowledged that the development of traditional terrestrial
communication technologies cannot provide all users with fair and high quality
services due to the scarce network resource and limited coverage areas. To
complement the terrestrial connection, especially for users in rural,
disaster-stricken, or other difficult-to-serve areas, satellites, unmanned
aerial vehicles (UAVs), and balloons have been utilized to relay the
communication signals. On the basis, Space-Air-Ground Integrated Networks
(SAGINs) have been proposed to improve the users' Quality of Experience (QoE).
However, compared with existing networks such as ad hoc networks and cellular
networks, the SAGINs are much more complex due to the various characteristics
of three network segments. To improve the performance of SAGINs, researchers
are facing many unprecedented challenges. In this paper, we propose the
Artificial Intelligence (AI) technique to optimize the SAGINs, as the AI
technique has shown its predominant advantages in many applications. We first
analyze several main challenges of SAGINs and explain how these problems can be
solved by AI. Then, we consider the satellite traffic balance as an example and
propose a deep learning based method to improve the traffic control
performance. Simulation results evaluate that the deep learning technique can
be an efficient tool to improve the performance of SAGINs.
