Protocols for multi-satellite networks

The unique features of a multisatellite network, which distinguish it from ordinary terrestrial networks, are the large propagation delay on the links, the constant changes in the network topology, and additional constraints such as limitation on power consumption. It is noted that ordinary protocols, which are designed to operate in stable, benign environments, will perform poorly under the dynamic conditions of multisatellite network. The author analyzes the limitations to existing protocols and describes protocols, such as routing, topology control, and reliable transport, that are suitable for multisatellite networks
