摘    要:提出一种基于布尔运算的无线传感器网络TOA定位新算法.算法针对室外定位,通过实验测得TOA测距误差的先验统计规律.在进行TOA定位时,算法首先根据测距值和先验统计参数建立同维布尔矩阵,然后利用矩阵运算和平方差判别式确定未知节点的估计位置.仿真和实验表明,与最小二乘(LSE)定位算法和优选残差加权(ORwgh)定位算法相比较,本文算法具有更好的定位精度,且在信标节点数大于6时具有更小的定位耗时.

关 键 词:无线传感器网络  定位  布尔运算

Abstract:A novel TOA-based localization algorithm for wireless sensor network is presented. It gets the priori statistical regularity of TOA ranging errors in outdoor environment before starting the localization. When localization begins,it partitions the whole nodes placement area into coarse-grained grids and constructs some Boolean matrixes corresponding to each ranging values and the priori statistical parameters. These matrixes are with the same number of rows/columns as the coarse-grained grids and can be used...
