Abstract: Aiming at the problems of lower location coverage rate for APIT location algorithm in Wireless Sensor Network(WSN), an improved algorithm called IAPIT is proposed. The performances of these two algorithms are compared in terms of different anchor ratios, different communication radius of nodes and the same anchor ratio node. Simulation experimental results show this improved algorithm has higher location coverage rate.

摘要： 针对无线传感器网络中APIT定位算法定位覆盖率不足的问题，提出一种改进的IAPIT算法，并从不同的锚节点比例、节点通信半径以及同一锚节点比例等方面比较2种算法的性能，仿真实验结果表明，IAPIT定位算法在定位覆盖率上有明显提高。
