A flexible bandwidth reservation scheme for handover management in LEO satellite systems

摘要

This paper proposes a new Flexible Bandwidth Reservation Scheme (FBRS) for handover management and call admission control in Low Earth Orbit (LEO) satellite systems. FBRS mainly aims to the QoS enhancement of multi-service systems. Compared with the other schemes, FBRS has a better performance in call dropping probability and call blocking probability. Moreover, considering the complexity and bandwidth utilization, FBRS outperforms the other schemes. An analytical model has been developed. Simulation results demonstrate the effectiveness of the proposed scheme.
