A Multi-objective Network Optimization Algorithm Based on QoS in Distributed Constellation Networks

This paper proposes and analyzes a multi-objective optimization algorithm based on QoS in distributed constellation networks, combining the topology and routing algorithm to optimize and reconstruct the network, a new heuristic networking scheme is also proposed to balance the network cost and the requirement weight. The algorithm is capable of minimizing the total network delay, improving the link utilization and achieving optimization combined with multi-QoS. The simulation results show that our algorithm and scheme can meet the needs of different network designs, optimize the performance and solve the problem of dynamic networking and network reconstruction, providing a basis for the research in combination of topology and routing in satellite networks.
