Abstract

Abstract: Low earth orbit (LEO) satellite networks have become the promising approach to provide broadband internet access service and have attracted the interests from both academy and industry. In this paper we review the related work of beam-hopping and find that most of the existing beam-hopping schemes are designed for GEO satellites and cannot be used for LEO satellites. Therefore, the beam-hopping system for the LEO mega-constellation is constructed in this worh. Due to the limited onboard resource and uneven traffic demand distribution, we propose a wide beam combined with dynamic beam-hopping scheme, which acquires signaling information from a wide beam to assist the spot beam to perform a communication scheme of the beam hopping on-demand service. The simulation results show that the beam-hopping scheme achieves better throughput performance than the fixed-beam scheme when the traffic demand distribution is uneven.

Key words: LEO satellite, beam-hopping, throughput
