摘要
无线传感器网络在目标跟踪应用中的优势主要体现在跟踪更精细可靠且及时隐蔽,但是由于传感器网络中没有中心控制机制,无线通信的带宽有限,这就要求采用合理的跟踪策略,高效的分布式信息处理算法。将'adhoc跟踪群'的概念移植到面向跟踪的无线传感器网络中作为传感器的组织策略,并和适用范围较大的粒子滤波相结合实现跟踪任务。仿真实验证明,在不影响跟踪精度要求的情况下,此方案能够降低通信能量开销。
The application of wireless sensor network in mobile target tracking is more precision, reliable, effective, covered than traditional systems, communication is limited, Therefore, it is but there are no center controlling system and the bandwidth of wireless necessary to use tracking plan and effective distributed tacking algorithm are necessary. In this paper, we impose ＂ad hoc tracking group＂ in wireless sensor network, and combine organization of sensor nodes with particle filtering applied in tracking. Simulations show this method can decrease energy expenditure and meet tracking precision.
