This paper discusses the tree a core data structure of one kind of project progress management software,and the implementation and optimization of algorithms of searching and traversal. In the algorithm D&C method is used throughout the process. We also try to change method of backtracking some key nodes so as to increas the speed of traveling throughout the tree.
提出了一种与节点位置无关的、能量感知的无线传感器网络覆盖控制协议EACCP(an Energy-Aware Coverage Control Protocol for wireless sensor networks),EACCP采用基于节点分层成簇的思想,根据节点邻居平均能量与自身剩余能量等参数竞选活动节点.理论分析与模拟实验表明EACCP协议不但能够提供高质量的网络覆盖率,而且可以有效地适应于节点能量异构的网络应用场景,并且减少活动节点选取过程中的控制消息开销.
