- 摘要:
- 针对无线传感器网络节点容易产生数据漂移的问题，提出了一种新型的跟踪和校准节点数据流漂移的算法。首先使用基于遗传算法优化的BP神经网络对目标节点和其邻居节点间的时空相关性进行建模，以获得目标节点的预测值，再使用卡尔曼滤波器跟踪和校准该节点的数据漂移。针对不同的真实数据集进行仿真实验显示，该方法相较于其他对比方法模型预测精度更高，漂移校准性能更好。实验结果表明，该算法可以精确地校准传感器节点的数据漂移，提高节点数据的可靠性。
- Abstract:
- Data drifts easily occur in wireless sensor network. To solve this problem, we propose a novel algorithm for tracking and calibrating the drifts of sensor data stream. First, backpropagation (BP) neural network optimized by genetic algorithm is applied to model the spatio-temporal correlations between the target node and its neighbor nodes to predict the value of the node, and then, the data drift of the node is tracked and calibrated by a Kalman filter. The simulation results using different datasets demonstrate that this method has superior prediction accuracy and calibration performance, compared with other methods. The experimental results show that this method can accurately calibrate the sensor drift and improve the reliability of node data.
