| 摘 要： | 对基于无线传感器网络(WSN)的目标跟踪机制进行了研究,采用一种分段线性拟合的方法对做正弦运动的目标进行跟踪,该方法是利用目标位置历史数据序列建立直线方程,用此直线方程预测目标未来时刻的位置及速度,实现对目标实时预测.仿真试验结果表明,该方法与滑动窗多项式拟合法相比具有计算量小、精度高的优点,更加有利于实现对目标的跟踪.

| Abstract: | The target tracking mechanism based on the WSN is studied.A segmental linear fitting method is adopted to track the target which is moving at sinusoid.By using the historic data sequence of the target position for building a straight line equation,and then using the equation for predicting the target's position and velocity at the future moment,the real-time prediction of the target is implemented.The simulation results demonstrate that,compared with sliding window polynomial fitting,this method has smaller calculation and higher-accuracy,it is more suitable for real-time tracking of the target. |
