【摘要】：针对异构密集网络中基站密度增大带来的网络能耗过高问题,提出一种异构网络中高能效的微基站部署方法。首先,考虑微基站候选位置可行性以减轻环境条件的影响;其次,在不同的用户分布状态下对优化目依概率进行加权,增强了对不同用户分布场景的适应性;最后,通过对微基站部署数目、位置和功率配置的联合优化来提升系统能效,并提出了一种高能效的微基站部署算法。仿真表明,与仅优化微基站数量和部署位置的方法相比,所提方法提升能效最高达26%。实验结果表明,相对于不考虑功率的部署方法,所提出的联合优化方法能够有效提升系统能效,同时验证了微基站功率对异构网络能效的影响。
[Abstract]:In order to solve the problem of high energy consumption caused by the increase of base station density in heterogeneous dense networks, a method of deploying micro-base stations with high energy efficiency in heterogeneous networks is proposed. First of all, considering the feasibility of microbase station candidate location to reduce the impact of environmental conditions; secondly, in different user distribution states, the optimization items are weighted according to the probability to enhance the adaptability of different user distribution scenarios. By optimizing the number, position and power configuration of the microbase station, the system energy efficiency is improved, and an efficient microbase station deployment algorithm is proposed. Simulation results show that compared with the method of optimizing the number and deployment location of microbase stations, the proposed method can improve energy efficiency up to 26 times. The experimental results show that the proposed joint optimization method can effectively improve the system energy efficiency compared with the deployment method without considering the power, and verify the effect of micro-base station power on the energy efficiency of heterogeneous networks.
