摘要 针对无线传感网现有跟踪算法精度低、能耗高等问题,研究一种能量高效的目标跟踪算法.该算法提出基于Voronoi图的节点休眠调度机制,在节约能量的同时保证监测区域的网络覆盖质量.然后分析节点间的位置拓扑关系对定位精度的影响,并通过合理选择信标节点实现目标的定位跟踪.仿真结果表明,该算法在能量效率、跟踪精度与稳定性方面表现出较好的性能. 针对无线传感网现有跟踪算法精度低、能耗高等问题,研究一种能量高效的目标跟踪算法.该算法提出基于Voronoi图的节点休眠调度机制,在节约能量的同时保证监测区域的网络覆盖质量.然后分析节点间的位置拓扑关系对定位精度的影响,并通过合理选择信标节点实现目标的定位跟踪.仿真结果表明,该算法在能量效率、跟踪精度与稳定性方面表现出较好的性能.
