A DTN routing scheme for quasi-deterministic networks with application to LEO satellites topology

The authors propose a novel DTN routing algorithm, called DQN, specifically designed for quasi-deterministic networks with an application to satellite constellations. They describe that their proposal efficiently forwards the information over a satellite network derived from the Orbcomm topology while keeping a low replication overhead. They compare their algorithm against other well-known DTN routing schemes and show that they obtain the lowest replication ratio without the knowledge of the topology and with a delivery ratio of the same order of magnitude than a reference theoretical optimal routing.
