针对移动锚节点的定位问题,提出一种基于3个移动锚节点的与距离无关的定位算法,该算法具有避开因测量距离的需要而导致的高硬件成本和高能耗等的功能。主要思想是3个锚节点规则移动遍历整个传感区域,移动过程中实现未知节点的定位。仿真实验结果表明,该算法能够提高节点的定位精度。
Aiming at the location problems of mobile anchor nodes,a range-free localization algorithm based on three mobile anchor nodes is proposed,which has the characteristic to avoid high hardware cost and enormous energy consumption because of the demand to measure range between two mobile anchor nodes.The main idea of the proposed algorithm is that three anchor nodes traverse the entire sensing areas by rules specified so that the unknown nodes can be located.The results of the simulation experiments show that the proposed algorithm can improve the positioning accuracy of the nodes.
