提出一种包含两层模糊逻辑的室内定位方法,第一层模糊逻辑用来计算检测点与参考点之间的相似程度;第二层模糊逻辑综合考虑检测点RSS矢量值与参考点RSS矢量值的欧氏距离和相似程度,计算检测点的位置坐标.在仿真实验中,用无线路由器构建室内无线网络,以采集到的Wi-Fi信号强度数据为基础,将提出的方法与常用室内定位算法的定位精度进行对比,验证了所提方法的有效性和精确性.
An indoor location approach with two-level fuzzy logic was proposed,in which,the first fuzzy logic calculates the similarity between reference point and test point,and the second one has Euclid distance and similarity between test point' s RSS vector and reference point' s RSS vector considered to calculate the location coordinate.In simulation experiment,the wireless routers were employed to construct an indoor wireless network.Basing on Wi-Fi intensity acquired and comparing the proposed approach with other conventional approaches prove the validity and accuracy of this proposed approach.
