摘要
无线通信的能耗问题受到越来越多的重视,能量效率成了5G网络中三大效率特性之一。一般而言,流量负载较低时,基站资源利用率也相对较低,造成基站资源浪费。为解决这个问题,提出一种基于距离感知的动态基站关闭算法。该算法通过动态关闭多余的基站来降低网络能耗,在满足基站负载均衡的条件下,通过估计用户与其关联基站的距离,计算可关闭基站的最大数目。仿真结果表明,所提算法较基于随机关闭的基站节能算法,明显地降低了能耗,并将平均节能百分比提高到88%。
The issue about energy consumption of wireless network attracts more and more attention and becomes one of three energy efficiency features in 5G. In general, resource utilization of BS is low when traffic load is not high, caused resource waste. To solve this problem, a new dynamic BS switch off algorithm based on distance-aware is proposed. This algorithm achieves a significant energy saving by dynamically switching off underutilized BS. In the premise of satisfy the network requirements of load balancing, the number of underutilized BS is calculated by estimating the distance between the User Equipment and their associated BS. Simulation results show that this proposed algorithm has a better performance in energy saving percentage compares to random energy saving algorithms, increase the average percentage of energy saving to 88%.
