Cooperative Beam Management Mechanisms for Federated Satellite Networks

Satellite networks are expected to play a key role in 6G and beyond. As demand grows, more operators are entering the market, leading to both competition and collaboration through resource sharing - similar to how the Internet developed into a network of networks. We envision a federated satellite network where operators work together for mutual benefit. To support this, we propose a cooperative beam management framework called federated satellite cooperative beam management (FSCBM). Unlike most existing approaches that focus on the Internet or simple satellite cooperation, FSCBM allocates network resources in a dynamic topology to increase capacity, using time slot and power allocation in resource-limited situations. We also develop cost models and introduce an efficient budget-constrained auction algorithm. Simulation results show that our solution significantly improves capacity and reduces cost, making it one step further toward the vision of the federated network of satellite networks.
