无线传感器网络目标探测定位跟踪问题研究

Research on Detection,Localization and Tracking of Targets in Wireless Sensor Networks

为在低耗能下完成更为精确的目标全程跟踪,提出了基于动态子网思想的目标探测定位和跟踪算法,并按照目标跟踪流程分别从簇头选择、目标探测、目标定位和目标跟踪4个阶段设计.仿真结果表明,相比于全网激活和固定子网策略,本算法在定位误差、预计误差和整体能耗三项指标中均处于最佳地位,有着极强的性能优势.

Aimed for detection, local get tracking p calization, and fixed network at accurate all-the-way target tracking with the low energy consumption,an algorithm lzatlon rocesswas and tracking of targets designed according to tracking. The simulation results strategy, this algorithm is found was proposed based on dynamic sub-networks, and the tar- the four phases, cluster head selection, target detection, loshow that, compared to the whole network activation and to be better in ergy consumption,having a significant advantage over other positioning error, estimation error, overall en- methods.
