VLC/RF异构网络融合小区缩放的功率控制与用户关联联合优化
Joint optimization of power control and user association for cell scaling in VLC/RF heterogeneous network integration
摘要
Abstract
Radio frequency(RF)wireless communication systems face issues of spectrum scarcity and access congestion.Integrat-ing visible light communication(VLC)with RF can complementarily achieve advantages of high data rates and broad coverage.For indoor hybrid VLC/RF heterogeneous network scenarios,a joint optimization method that combines cell scaling power con trol and user association has been proposed to maximize the total system transmission rate under power and quality of service(QoS)constraints for users.By modeling this problem as a multi-variable coupled mixed-integer nonlinear programming(MINLP)opti-mization problem,it is effectively solved using the BARON optimization solver.The simulation results show that the integrated cell scaling in VLC/RF heterogeneous networks can achieve superior power allocation and user association,thereby enhancing the overall system transmission rate.关键词
