传感器网络层级结构路径覆盖控制方法

针对路径覆盖节点控制策略问题,利用路径覆盖的特点,提出了一种基于层级结构的节点覆盖控制方法.通过对节点感知监测目标的先后顺序,在保障不丢失监测目标的前提下,建立了节点层级模型和关联模型,设计了以开启节点数目和均衡能耗为优化目标的覆盖控制策略.仿真结果表明,该方法较基于冗余节点的覆盖控制方法,可以有效地改善节点的能耗效率,从而起到提高网络服务质量,延长网络寿命的目的.

Coverage control strategy based on hierarchy for path coverage in wireless sensor networks

Taking advantage of the unique characteristic of path coverage,a method based on hierarchy has been proposed for path coverage control strategy.Through analyzing the order that sensor nodes detect target objects,the sensor node hierarchy model and correlation model are established without ignoring any target objects.Furthermore,the coverage control strategies with two optimal objectives that are the balance of energy consumption and the number of active sensor nodes have been proposed.Comparing with the cov...
