Routing Space Internet Based on Dijkstra's Algorithm

Earth observation data will be moved through satellite constellations to ground stations by space internet. Routing observation traffic in this environment is constrained by factors such as satellite orbits, satellite capabilities, observation schedules, ground station schedules, and rapidly evolving natural events. Among many global routing algorithms, Dijkstra Algorithm is mostly preferred as it is faster as compared to any other algorithm and its implementation is easier. For this reason, this paper implements a routing algorithm of Dijkstra for space networks under constraints mentioned above.
