无线传感器网络中移动目标的定位与跟踪

对侵入无线传感器网络中的目标,提出了一种移动节点和静态节点相结合的定位与跟踪方式.静态节点可以发现侵入传感器网络中的目标,移动节点与静态节点配合进一步确定目标的具体位置.仿真实验验证表明:该方法可以减少大规模的频繁移动节点,不需要过多地对移动节点的选择和运动进行特别复杂的计算,具有较好的定位精度和鲁棒性,对多目标的定位与跟踪研究有一定的启发作用.

Localization and tracking of mobile target in wireless sensor networks

Aiming at target intruding into wireless sensor networks (WSNs),a method of positioning and tracking is proposed based on combination of mobile nodes and static nodes.Static nodes can find the target intruding into sensor network,the mobile nodes and the static nodes will determine the specific location of the target further.The simulation results show that the method can reduce the mobility of the nodes in large scale,also it does not need too much complex calculation on selection and motion of the mobile nodes,it has better localization precision and robustness and has certain help for multitarget localization and tracking research.
