| 摘 要： | 从目标跟踪(用多个静态已知位置的传感器跟踪和预测一个移动的目标)的逆向方法出发,提出一种采用可移动节点在未知节点布设区域上空进行行列扫描,同时向未知节点发射相应标识信号给未知节点的定位算法--LA-SCAN.它具有至少两个优势:1)由于未知节点只需接收第一次标识号,用于节点定位的通信能耗极低;2)未知节点只需要移动节点移动间距、布设区起点位置和接收到的标识号即可计算m估计坐标.理论分析和仿真结果表明LA-SCAN算法具有高的性能表现.

| Abstract: | Using dual target tracking(static location-aware sensor tracking and moving target position/speed predicting),we utilize a moving location-assistant(LA) to scan location-unaware sensors in the deployed area by row(column) and construct grids.LA only sends ID;at the same time,location-unaware sensors receive the first arrived ID merely.The proposed system is called LA-SCAN.LA-SCAN has at least two significant benefits compared with other methods applicable:1) since nodes listen passively and only receive one... |
