摘要
针对无线异构网络节能问题,文中提出了一种可依据流量动态变化进行自动调整的无线异构网络终端接入控制机制。首先分析了异构蜂窝网络系统模型,包括业务量模型和异构基站能耗模型,进而提出了满足节能条件的优化目标模型,最后设计了应用于补偿过程的智能优化算法。通过仿真验证,该机制能够确保网络通信业务服务的柔性覆盖,在保持区域网络服务质量和稳定性的同时,节省该区域约18%的能耗,且网络恢复复杂度较低。
Aiming at energy-saving for wireless heterogeneous networks,we propose a terminal access control mechanism for heterogeneous wireless networks that can be automatically adjusted based on dynamic changes in traffic volume.Firstly,the system model of heterogeneous cellular networks is analyzed,including a traffic model and power models of base-station.Then,an optimization objective model that satisfies the energy-saving conditions is proposed.At last,an intelligent optimization algorithm applied in compensating process is designed.Through simulations,the proposed mechanism can ensure flexible coverage of network communication service,maintain the signal quality and stability of regional network,and save about 18%of energy consumption in the area.While,the complexity of network recovery is low.
