摘　　要：为有效解决无线传感器网络对具有声音特性移动目标的跟踪问题,该文利用声音随距离的能量衰减模,并结合声强特性,给出了基于动态组管理机制的目标跟踪方法。仿真实验结果表明无线传感器网络中基于声强特性的方法,能够有效实现对移动目标跟踪,结合Kalman滤波算法提高了实验结果的跟踪精度。To solve the tracking problem of maneuver target with acoustic characteristic in wireless sensor network,according to the attenuation model of acoustic energy with distance,an acoustic-energy based target tracking algorithm is proposed based on dynamically greedy group management scheme.The simulation results show that the proposed algorithm can effectively track the target and the tracking error can be decreased by using Kalman Filter.
