二进制无线传感器网络目标跟踪问题的研究

Overview on Target Tracking Methods in Binary Wireless Sensor Networks

无线传感器网络是近几年发展起来的一门新技术,其研究的重点之一是目标跟踪问题。二进制传感器网络由于其低廉的布设代价、体积小、低能耗以及传感器节点简单,正得到越来越多的关注并用于目标跟踪。目前二进制无线传感器网络中的目标跟踪方法主要分为两大类:基于分段线性拟合的方法和基于粒子滤波的方法。现分别归纳总结现有二进制无线传感器网络中目标跟踪的两大类方法的研究成果并指出其优缺点以及未来的研究方向或需要完善的工作。

Wireless sensor networks are one of new technologies in recent years and target tracking in the networks is one of the research emphases. The binary sensor networks are becoming more attractive due to the low cost deploy- ment,small size,low energy consumption and simple operation and data communication of the sensors. Therefore, it is taken into consideration in target tracking. The methods availably used in target tracking of binary wireless sensor net- work can be cataloged into two classes,piecewise linear approximation based method and particle filter based method. The current research results were analytically presented,and the future work was also pointed out.
