摘要
针对APIT-3D算法中常见的In-to-Out Error和Out-to-In Error两类误判问题,提出了一种VJ-APIT算法。该算法通过改进内点测试方法和RSSI测距误差两个方面以提高定位。改进算法无需额外硬件的支持。仿真实验表明,该算法在不同通信半径和锚节点比例的网络均有良好的定位性能。
Aiming at two common misclassification problems about in-to-out error and out-to-in error in the APIT-3D algorithm,a tetrahedral volume judgment APIT algorithm（ VJ-APIT） is proposed. The algorithm can improve the positioning by improving the interior point test method and the RSSI ranging error. The improved algorithm has low complexity and does not require any additional hardware support. The simulation results show that the proposed algorithm keeps high localization accuracy under different anchor density and communication radius.
