An inter satellite link handover management scheme based on link remaining time
In this paper, an inter satellite link handover management scheme based on link remaining time (HM-LRT) is proposed. Since the satellites move in a regular pattern, the remaining time of inter satellite links going down can be predicted. Based on link remaining time and other information, our link handover management scheme changes the data transmission routes to prevent data packets from going into links that are going to be handed off, so as to reduce the data loss and guarantee the QoS of the satellite communication network. Experiments show that the routing algorithm with HM-LRT outperforms the original routing algorithm.
