Resource Allocation in Beam Hopping Communication System

Beam-Hopping provides satellite systems with an additional dimension of agility making it possible to adjust the allocation of the scarce satellite spectral and power resources to the demand which varies in space and geography as well as with time. Provided such flexibility, it has a great potential in enhancing communication satellite capacity. An effective resource allocation mechanism which can meets future demands flexibly is urgently needed in order to achieve the best user communication quality and to provide more users with more satisfactory service. The existing beam steering mainly focus on covering the beam position which largest demand the spectrum resources and do not fully utilize the advantages brought by the flexibility in beam range. In this paper, we propose a beam resource management algorithm that adjusts the beam size according to the service distribution, which can make more users accessible to make full use of beam bandwidth resources by covering more beam positions. Simulation results show that the proposed algorithm can effectively reduce packet loss rate, improve the quality of service (QoS)” and guarantee service priority.
