基于功率配置和关联管理的WLAN能耗优化算法
Optimization of WLAN energy consumption based on power configuration and association management
摘要
Abstract
To save the energy consumption and guarantee network performance in wireless local area networks (WLANs),an energy consumption optimization algorithm based on power configuration and association management is proposed.First,a fine-grained energy consumption model is adopted to define the power of access points (APs),and the optimization problem is formulated as an integer linear programming (ILP) model.It aims to minimize the energy consumption of APs through scheduling the radios to be active or sleeping,configuring the transmit power,and managing the associations between APs and users,while satisfying the bandwidth requirements of users.Then,an efficient heuristic algorithm is proposed by iteratively choosing an AP to be active,selecting the transmit power level and determining user associations.In each iteration,the AP and its power level with the maximum value of energy efficiency is selected.Simulation results show that the proposed algorithm can save energy consumption effectively.It also demonstrates that the algorithm has significant advantages in execution efficiency,and can be well applied in large-scale WLANs.关键词
