摘    要:探讨了无线传感器网络(WSN)定位技术的意义,研究基于移动锚节点的测距定位技术;设计了移动锚节点运动轨迹,在利用无线电与超声波到达时间差(TDOA)测得锚节点到待定位节点距离的情况下,给出了一种新的定位算法——三边质心定位算法,该算法通过求解待定位节点的定位近点所构成几何图形的质心来完成定位;仿真结果表明,该定位技术能够明显减小定位误差与锚节点数量。

关 键 词:无线传感器网络  移动锚节点  到达时间差  定位算法

Abstract:The significance of localization technology for wireless sensor network is discussed,and a range-based localization system using mobile anchor node is studied.After designing the trajectory for mobile anchor node,and propose a new localization algorithm,namely trilateral-centroid localization algorithm in the case of measuring mobile anchor node to unknown node distance using the time difference of the arrival radio and ultrasonic.The simulation results show that the localization system can significantly re...
Keywords:wireless sensor network (WSN)  mobile anchor node  time difference of arrival (TDOA)  localization algorithm
