Survey on Dynamic Routing Networking Methods in Integrated Satellite-Terrestrial Network.

With the fast developing and commercial deployment of Integrated Satellite-Terrestrial Network (ISTN), the communication efficiency within ISTN have become the key research prospect of the future 6G network. This paper investigates the current study status of dynamic routing networking methods in ISTN. On the one hand, in the classification of single-layer dynamic routing networking, this paper introduce several outstanding routing algorithms based on virtual topology methods and virtual nodes methods. On the other hand, in the classification of multi-layer dynamic routing networking, this paper also introduce several efficient routing algorithms regarding Quality of Service (QoS) and balanced traffic. In the end, this paper gives potential opportunities for the enhancement of dynamic routing networking technology in the future.
