Abstract
In this paper, a multi-objective optimization design methodology of low Earth orbit (LEO) satellite broadband network is proposed. Firstly, the quality of service (QoS) metrics and network stability factor (NFS) are established for the LEO satellite network. Then, a multi-objective optimization model for LEO satellite network design is constructed based on the constraints of permanent Inter-satellite Link (ISL) and QoS metrics. In addition, a constrained multi-objective optimization algorithm is designed by integrating NSGA-II with constraints handling. Finally, the simulated results validate the effectiveness of the proposed method and show that this approach provides a new idea for the optimization deployment of the network architecture.
