Research on Target Detection Localization and Tracking in Wireless Sensor Network

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四个阶段设计。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均处于最佳地位，有着极强的性能优势。

To complete more precise target tracking in low energy consumption, a positioning and tracking algorithm in target detection based on the dynamic network idea is proposed, and in accordance with the target tracking process, the design is completed respectively from the cluster head selection, target detection, target localization and tracking four stages. The simulation results show that, compared to the whole network activation and fixed network strategy, this algorithm is the best in error positioning, prediction error and the overall energy consumption these three index, and it has a strong performance advantage.
