LTGAT DATA

The datasets employed in this study were constructed from two primary sources: contact plan files generated using STK and simulation log files produced by DTNSim. Together, these inputs provided the foundation for building a time-varying graph, extracting ground-truth delivery outcomes, and deriving detailed node and edge features. The log files captured both successful and failed bundle deliveries under CGR, enabling the formation of datasets that accurately represented the dynamic operational behavior of the network. The feature design was carefully formulated to reflect the operational characteristics of the lunar DTN environment. Node features, defined with a dimensionality of three, encoded the categorical roles of the network entities, distinguishing between lunar relay satellites, lunar ground stations, and terrestrial DSN ground stations. Far-side lunar sensors, although included in the topology as data sources, were excluded from routing participation and thus omitted from the node feature representation. Edge features, defined with a dimensionality of four, captured the temporal and physical properties of communication links, including contact start time, end time, available transmission rate, and link capacity.
