摘要
为对随机变化目标进行跟踪和监测,提出区域覆盖的无线传感器网络监测方法。通过建立哨兵节点监测事件的出现,在事件发生区域采用伸展等边三角形进行伸展,形成对目标活动范围的完全覆盖;伸展等边三角形内部节点和顶点节点构成二级网络,实现事件监测和数据传输;根据事件边界的伸展等边三角形影响面积变化,采用提前一步监测和滞后一步取消监测对事件的发展变化做出反应。实验结果表明,该算法有利于随机变化事件的监测和能耗的均衡化,延长网络生存期。
To track and monitor random variable targets,a wireless sensor network monitoring method based on region coverage was proposed. The occurrence of the event was monitored through the sentinel node,and the extensional equilateral triangle was used in the event area to form a complete coverage of the target. A two level network was composed of the internal nodes and vertex nodes in extensional equilateral triangle,which implemented event monitoring and data transmission. According to the change of area in the boundary triangle,the change of events was judged. One step monitoring in advance and delay one step to cancel were used in target monitoring. Experimental results show that the proposed algorithm is beneficial to the monitoring of random change events and the balance of network energy consumption. It prolongs the lifetime of the network.
