Hierarchical Routing is a network routing strategy that organizes nodes into multiple levels or regions to improve scalability and efficiency in large networks. Instead of maintaining full routing information for all nodes, each level manages aggregated routing data, reducing overhead and enabling faster decision making. It is widely used in systems such as the Internet and satellite networks to support dynamic topology changes and efficient data forwarding.
We propose a mobile orbital domain-based hierarchical routing scheme which addresses the challenges posed by constant satellite movement and the resulting dynamicnetwork topology, thus significantly improving the routing scalability and efficiency in satellite networks.
