【摘要】：为实现WLAN节能并保证网络性能,研究并提出了一种基于功率配置和关联管理的WLAN能耗优化算法.首先,采用细粒度的能耗模型来定义AP功率,并利用整数线性规划(ILP)对能耗优化问题进行形式化描述,即通过调度射频接口的活跃/休眠状态,配置AP的信号发射功率,以及管理AP与用户的关联关系,在保证用户带宽需求的前提下,降低网络能耗.然后,提出一种高效的启发式算法,以迭代的方式选择开启的AP及功率级,并确定所关联的用户.在每次迭代中,以最大化能效的策略进行AP及其功率级的选择.实验结果表明,该算法能有效实现WLAN节能,并具有较高的运行效率,能够适用于大规模的WLAN.
[Abstract]:In order to realize WLAN energy saving and ensure network performance, a WLAN energy consumption optimization algorithm based on power configuration and association management is studied and proposed. Firstly, the AP power is defined by a fine-grained energy consumption model, and the problem of energy consumption optimization is described by integer linear programming (ILP), that is, the AP signal transmit power is configured by scheduling the active / dormant state of the RF interface. The relationship between AP and users is managed to reduce network energy consumption on the premise of guaranteeing user bandwidth requirements. Then an efficient heuristic algorithm is proposed to select the open AP and power level iteratively and to determine the associated users. In each iteration, the AP and its power level are selected with the strategy of maximizing energy efficiency. The experimental results show that the proposed algorithm can effectively realize the energy saving of WLAN and has a high running efficiency, and it can be applied to large-scale WLAN.
