摘　　要：针对企业无线网络的特点,提出一种基于可控公平性约束的网络功率控制优化方法.该方法可根据节点受干扰的程度,灵活设置参数,以反映节点对公平性的不同需求,可在不同应用场景下对网络吞吐量和公平性指标进行适当的折中.仿真结果表明,相对于最大化总吞吐量准则和最大最小公平准则,采用可控公平约束的企业无线网络功率控制算法,具有更好的灵活性,可更精细地调节节点间功率分配的关系,在抑制干扰的同时,保障网络性能的相对均衡和公平.For the characteristics of enterprise wireless network,a method based on controllable fairness constraint was proposed to optimize the process of network power control. The method can set the parameters of the controllable fairness constraint flexibly to reflect the different fairness demand according to the different interference of the nodes,and compromise the network throughput and fairness appropriately.Simulation shows that,compared to maximize overall throughput and max-min fairness criteria,the enterprise wireless network power control algorithm with controllable fairness constraint is more flexible and can adjust power allocation relations more finely between nodes to guarantee the performance of network relatively balanced and fair while interference suppression.
