| 摘 要： | 为进一步降低二元探测传感器网络质心定位算法的计算复杂度和通信量、提高定位精度,推导出一种质心算法的递推公式,使用该递推公式可以大大减少定位的计算、存储和通信量;在递推质心公式的基础上,提出了一种基于节点探测到目标的次数的递推加权质心定位算法,从而提高了定位精度.对递推公式和加权质心算法进行了模拟仿真,结果验证了递推公式和加权递推质心算法的有效性.

| Abstract: | In order to decrease the complex computation and communication load,and improve the locating accuracy of the centroid locating algorithm in binary sensor networks,the following tasks were carried out.A recursive computing formula for centroid algorithm was deduced,which could greatly decrease computation,storage and communication load of object locating;a recursive weighted centroid algorithm was further presented based on the recursive centroid formula,which was employed for a node to detect an object as a... |
