Architecture design and intelligent management of space-air-ground integrated network

Abstract： In order to overcome the difficulties of cooperation between different networks caused by the complex structure and diverse services of SAGIN(Space-Air-Ground Integrated Network), a multi-dimensional management architecture of SAGIN based on Mobile Edge Computing(MEC) is proposed. The network system is divided into data layer, control layer and management layer. The network state information is collected and processed layer by layer and the network management strategy is formulated by MEC and forwarded layer by layer. The simulation platform based on the proposed architecture is built, and the network cooperation strategy is formulated through reinforcement learning method. The simulation results prove the effectiveness of the proposed architecture.
