Abstract
This paper proposes a routing scheme for low earth orbit (LEO) satellite networks, named congestion-based random-encountering routing (CTR) scheme. Firstly, forward agents migrate autonomously to explore paths from source to destination satellite, while back agents follow the path in the opposite direction. Meanwhile, data probability table of every satellite will be changed according to the condition of satellites which agents gather and estimate, eg. congestion, propagation and queuing delay between inter-satellite link (ISL). Finally, simulation is performed on a Courier-like constellation. Moreover, results show that the proposed scheme guarantees better quality of service (QoS), especially shorter end-to-end delay and lower packet loss ratio, for load balancing.
