| 摘 要： | 针对无线传感器网络的特点,在深入分析现有近似三角形内点测试(APIT)定位算法的基础上,提出一种改进机制,即区域混合感知的近似三角形内点测试(RMA_APIT)定位算法。该算法根据网络的部署情况,自动调整未知节点的定位区域并引入辅助节点对未知节点进行定位,从而提高定位精度。仿真结果表明,采用RMA_APIT定位算法,节点的定位精度和有效定位比都有较大提高。

| Abstract: | This work begins with a thorough investigation of APIT localization algorithm.On this basis,a region mixed-aware algorithm(RMA_APIT) is proposed.Based on the deployment of the network,RAM_APIT adjusts the positioning area of the unknown node automatically and introduces assistant nodes that used to position the unknown node,thereby improving positioning accuracy.Simulation results show that RAM_APIT algorithm improves positioning accuracy of a node and the ratio of effective localization nodes significantly. |
