Improved TDOA positioning algorithm for wireless sensor networks
Author(s): 
Pages: 117-120
Year: Issue:  16
Journal: Computer Engineering and Applications

Keyword:  到达时间差参考节点目标节点定位;
Abstract: 针对TDOA定位算法存在的不足,提出了一种改进算法.采用在同一节点上测量时差的方法消除了TDOA定位算法中对节点时间同步的要求,利用滚动平均法削弱了多径传播和随机噪声的影响.改进算法无需额外的硬件支持,计算量小,定位精度高,具有较好的实用性.
