Abstract

A reverse detection based QoS routing algorithm was developed based on the dynamic topology of low earth orbit (LEO) satellite constellation networks. This distributed algorithm has very low computational complexity, so it is suitable for on-board processing. This algorithm improves the autonomous operating capability and throughput of satellite networks. Simulations show that the algorithm has better performance than the static sequent snap shots algorithm with acceptable low overhead signaling.
