摘要
随着蜂窝移动网络中用户数的增加,蜂窝网从以前的单一架构转变为异构,基站的能量消耗也呈现出了指数型的增长。能量获取是一种新兴的技术,可以节省传统电网的能量并减少无线通信中的碳排放量。异构网络中的小区选择是影响系统性能的关键因素。从能量获取、能量协作、异构网络等方面考虑,提出了一种折中能量获取、能量消耗、负载均衡、接收速率等性能指标的小区选择算法。仿真结果表明,该算法可以减少基站对电网能量的需求,增加用户选择的可能,满足公平性和有效性,可适用于5G绿色通信。
As the number of users in cellular mobile networks increases,cellular network changed from the previous single architecture to heterogeneous architecture,base station energy consumption also showed an exponential growth.Energy harvesting is an promising technology to save on-grid power and reduce carbon emission in wireless communications.The cell selection in the HetNets is the critical factor of affecting network performance.In this paper,from the energy harvesting,energy cooperation,heterogeneous networks and other aspects,a cell selection algorithm is proposed,which can compromise energy harvesting,energy consumption,load balancing and other criteria.The simulation results show that this algorithm can reduce the base station′s demand for grid energy,increase the possibility of user selection,and satisfy the fairness and validity.It′s applicable to 5G green communications.
