A Distributive Localization Method for Wireless Sensor Networks Using Angle of Departure[J]. 2010, 44(2): 61-66.
针对现有无线传感器网络节点定位方法成本和复杂度较高的问题
提出了一种利用离去角度估计的分布式节点定位方法(AODL).锚节点利用阵列天线发射正交导频信号
从而使得各传感节点仅需配备常规的单天线系统便可获得导频信号的离去角度信息.结合锚节点的地理位置
各节点进而可进行自身的三维位置估计.AODL方法仅利用无线通信设备进行定位
节点的角度估计不需要配备阵列天线
具有低成本和低能耗的优点
同时各节点独立进行自身的角度估计和位置计算
是一种分布式的定位方法.仿真实验结果表明
对于100 m×100 m的定位区域
借助于4个装备3×3均匀面阵的锚节点
各传感节点在信噪比为15 dB时的平均定位误差可以达到1 m以内.
A novel distributive localization method using the angle of departure(AODL)is proposed to reduce the cost and complexity of existing localization methods for wireless sensor networks. The anchors emit time-division pilots to the network using multi-antenna system
and each sensor just utilizes single-antenna system to estimate the angle of departure(AOD)of the pilot
by which the sensor's position can be determined. The AODL only relies on radio transceivers
and the sensors estimate the angle information without the need of conventional multi-antenna system
so that the system complexity is greatly reduced. Moreover
the angle estimation and position calculation are conducted at each sensor in a completely distributed manner. The simulation results show that for a 100 m×100 m region
with the assistance of four anchors equipped with 3×3 uniform planar array
the average location error is within 1 m when the signal-to-noise ratio of each sensor is 15dB.
