随着无线数据业务爆炸性增长,无线通信系统日益产生巨大的能耗,已成为全球能源消耗的主要来源之一.为降低无线通信系统能耗,重点探讨超蜂窝架构下,提高网络能效的资源动态调度与优化方法.具体包括两方面:首先建模分析超蜂窝网络分离架构的能效,同时给出基于能效优化的基站自适应休眠策略;之后阐述超蜂窝网络时延与能效的折中关系,并研究能效和时延同时优化的协作策略和资源分配方案.
With the explosive growth of wireless data services, wireless communication systems have been increasingly generating huge energy consumption and have become one of the major sources of global energy consumption.In order to reduce the energy consumption of wireless communication systems, the focus is on the resource dynamics for improving network energy efficiency under the super-cellular architecture Scheduling and optimization methods, including two aspects: First, the energy efficiency of the separation architecture of the super-cellular network is modeled and analyzed; meanwhile, adaptive dormancy strategy of the base station based on the energy efficiency optimization is given; meanwhile, the compromise relationship between the delay and the energy efficiency of the super- Research collaborative strategies and resource allocation solutions that optimize energy efficiency and latency simultaneously.
