【摘要】：该文在两层异构网络架构下,采用泊松分布(PPP)建立基站分布模型,构建基于基站密度和业务负载的网络能效模型。分析基站密度对网络能效的影响,并根据网络业务流量的到达率对宏基站和小基站的密度进行联合优化,得到宏基站和小基站的最优联合密度,在保证网络服务质量的同时,使能效达到最优。仿真结果表明,在不同的网络业务需求下,通过基站密度的优化,在保证网络服务质量的同时,合理部署宏基站和小基站的数量,可使能效大幅度提高。
[Abstract]:In this paper, based on the two-layer heterogeneous network architecture, the base station distribution model is established by using Poisson distributed PPP), and the network energy efficiency model based on base station density and service load is constructed, and the influence of base station density on network energy efficiency is analyzed. According to the arrival rate of network traffic, the density of macro base station and small base station is jointly optimized, and the optimal joint density of macro base station and small base station is obtained. Under different network service requirements, the energy efficiency can be greatly improved by optimizing the density of base stations, while ensuring the quality of network service and reasonably deploying the number of macro base stations and small base stations.
