针对典型声学传感器构成的WSN(Wireless Sensor Network,无线传感器网络),提出了一种基于最优探测的移动代理WSN目标跟踪算法,通过移动代理采集当前时刻最优探测结果的节点数据集合,利用三边定位法对目标位置进行估计,根据卡尔曼滤波估计目标下一时刻位置和节点剩余能量条件,确定移动代理后续迁移节点。仿真结果表明提出的算法能够有效对WSN中目标进行跟踪,且误差较小。

For typical WSN consisted of acoustic sensor,a mobile agent WSN target tracking algorithm based on optimal detection a mobile agent based on optimal detection WSN target tracking algorithm,the optimal detection result by mobile agent to collect the current moment of node data collection,using the method of the positioning of the trilateral target location estimate,based on the kalman filter to estimate the target location and residual energy node of the next moment conditions,determine the migration of mobile agent subsequent nodes.The simulation results show that the proposed algorithm is effective for target tracking,and the error is small.
