摘要
分析了传感器网络在在目标跟踪过程中产生目标丢失故障的原因,在此基础上采用分簇设计思想,通过对跟踪目标移动速度的计算和目标搜寻区域的建立等方法,提出了目标丢失故障恢复新的算法和技术。通过仿真实验证明所提出的目标跟踪系统的目标丢失故障恢复算法和技术在延长传感器网络生存时间前提下能够有效解决跟踪目标发生丢失故障后目标快速恢复问题,并通过仿真实验比较说明了提出的方法在能量有效性方面优于其它的方法。
The reason why not being able to find the moving target during tracking is first discussed. Then by taking advantage of hierarchical clustering structures, an optimized recovery algorithm is presented to tracking moving targets with determining the speed of the target and the search region when they cannot be found. Finally, it is showed by simulations that the proposed algorithm is effective in extending the network lifetime and performing a quick recovery. By comparing simulating result with another algorithms', the more improvement of the proposed algorithm is demonstrated in energy efficiency.
