| 摘 要： | 对于移动目标跟踪,需要利用加速度或速度恒定的模型对其连续轨迹进行推断.在传感器网络环境下,利用无线传感器网络的冗余特点,提出了一种分簇结构和分时机制下采用流水线工作模式进行跟踪探测的方法,减少两次探测值之间的时间差,通过分析和仿真验证,该方法能够有效地降低对移动目标的跟踪误差.所设计的算法计算复杂度低,实现简单,满足无线传感器网络节点的计算能力要求.

| Abstract: | When tracking mobile target,the real-time trajectory of the mobile target is obtained through extrapolation method,while this method brings extrapolation error.Using nodes' redundancy characteristic of wireless sensor network,a method of target tracking based on time-slotted is presented and analyzed.And its reality arithmetic is designed too.The nodes only need one multiplication operation in arithmetic.The method is fit for nodes while the node has limit computing capability.The result of analysis and sim... |
