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OA北大核心
Joint optimization of power control and user association for cell scaling in VLC/RF heterogeneous network integration
射频(RF)无线通信系统面临频谱短缺和接入拥塞问题,而可见光通信(VLC)与RF融合可互补实现高数据速率和广覆盖优势.针对室内混合VLC/RF异构网络场景,提出了融合小区缩放的功率控制与用户关联联合优化方案,旨在功率和用户服务质量(QoS)约束条件下最大化系统总传输速率.通过将该问题建模为一个多变量耦合的混合整数非线性规划(MINLP)优化问题,并采用了优化求解器BARON进行有效求解.仿真结果表明,融合小区缩放的VLC/RF异构网络能够实现更优的功率分配和用户关联,提高了系统总传输速率.
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.
