面向卫星物联网的柔性波束调度与资源分配策略研究
Flexible beam scheduling and resource allocation strategies for satellite Internet of things
摘要
Abstract
Satellite communication systems based on multi-beam technology can provide strong support for massive ma-chine type communication application scenarios of 5th generation mobile communication technology as well as for next-generation communication visions,such as access and transmission of massive Internet of things(IoT)devices and ubiqui-tous communication.In the satellite IoT-oriented massive terminal application scenario,the traffic distribution of IoT ter-minals is non-uniform.Further,improving the communication resource utilization efficiency of multi-beam satellite sys-tems has become an important research direction.Multi-beam scheduling and wireless resource allocation are the key is-sues to improve the resource utilization and fairness of the system.Firstly,The coupling between beam scheduling and wireless resource allocation was analyzed.Subsequently,a joint optimization strategy for flexible beam scheduling and re-source allocation was proposed.The beam scheduling algorithm based on separated swarm optimization(SSO-BSA)was proposed to solve the flexible beam pointing coordinates,and an on-demand resource allocation algorithm based on ser-vice value degree(ORAA-SVD)was designed to provide flexible resource allocation for beams and IoT terminals.The simulation verifies the performance of the proposed algorithm and the benchmark algorithms under different traffic inten-sities for each metric.The simulation results show that the proposed algorithm has better performance than that of the benchmark algorithms in terms of fairness and resource utilization.关键词
