摘要
针对基于测距的三边定位算法定位精度节点间相对位置非常敏感问题,在探讨物联网技术应用于军事领域的无线定位时,提出了一种基于牛顿迭代法的无线传感器网络(WSN)定位新算法。仿真试验表明,该算法与已有算法相比,对节点间相对位置更具鲁棒性,显著提高了定位精度。
The accuracy of the trilateration localization algorithm based on the distance measurement is a sensitive problem to the relative positions of the nodes. To solve the problem, a new wireless sensor network localization algorithm based on the Newton iterative method is proposed when discussing the military application of internet of things （IOT） to the wireless localization. Simulation results show that the algorithm is more robust for the relative positions of the nodes, thus improving the positioning accuracy.
