摘要 在无线传感器网络的诸多应用中,迫切需要对事件发生区域或者数据来源进行定位,特别是在无锚节点的情况下。为此该文提出一种基于功率控制的质心定位算法(CLAPC),采用离散功率控制的方式对目标区域进行虚拟网格划分,从而确定包含未知节点的最小区域,在提升系统能效的同时,提高了节点的定位精度。算法无需部署锚节点,具有较高的实用性,仿真实验也进一步验证了算法的有效性。 A centroid localization algorithm（CLA） for wireless sensor networks is presented based on power control（CLAPC）.In this algorithm,the target area is divided into a series of grid cells by using discrete power control method,thus each intersection formed by these cells would be a minimal zone including the unknown nodes.As a result,CLAPC can enhance the energy efficiency of the network system and improve the precision of localization.The algorithm proposed in this paper is anchor-free localization and flexible in practice.The validity of CLAPC is evaluated and confirmed through extensive simulations.
