无线移动传感器网络的分布式目标跟踪算法

Distributed Target Tracking Algorithm for Wireless Mobile Sensor Networks

为了满足无线移动传感器网络(WMSN)的目标跟踪应用要求,提出了一种分布式目标跟踪算法,可使用节点引导保证WMSN的网络动态连通性;在传统分布式数据融合体系结构的基础上,结合平均一致性滤波器实现了低通信开销的优化分布式数据融合.仿真结果表明,该算法在WMSN中的目标跟踪效果良好,且数据融合性能优于传统分布式数据融合算法.

In order to satisfy the application request for target tracking in wireless mobile sensor net- works（WMSN）, a distributed target tracking algorithm is presented. This algorithm includes two parts, one is using node leading to ensure the dynamic connectivity of WMSN, and the other is com- bining average consensus filter with traditional distributed data fusion architecture to realize the opti- mizing distributed data fusion with low cost of communication. Simulations show that target tracking effect of the proposed algorithm is good in WMSN and the performance of data fusion is better than traditional distributed data fusion algorithm.
