Performance Analysis and Optimization of the Navigation Satellite Network Node Transmission Model

Aiming at the problem of preferential competition of information caused by the fusion of terminal nodes and routing nodes in navigation satellite network, a terminal-prioritized network node transmission model is proposed. The characteristics of topology, routing, and service information path of the navigation satellite network was analyzed, and the terminal-first network node routing model and the mixed-preferred network node routing model was designed. Simulations based on the packet delivery delay and network throughput index show that the terminal-first network node routing model can achieve higher transmission performance.
