摘要
如何有效地部署节点是传感器网络系统设计中首要考虑的问题,它直接影响网络的性能和寿命。目前节点部署环境考虑无限空间或规则区域,但是实际部署环境如战场、森林检测等是有边界且边界形状不一的环境。文中提出了一种低能耗的无线传感器边界节点部署方案,并命名为V-HART方案。一方面方案基于六边形网格的配置策略,减少中心节点数量;另一方面方案将边界节点放置在六边形中垂线处的二维监测区域,节点数量减少,能耗降低。仿真结果显示,相比于凸边形区域节点部署,V-HART使用的节点少,具有能耗小、可靠性高和使用节点少等优点。
How to effectively deploy sensor network node is a primary consideration in system design issues, which directly affect the network performance and lifetime. Consider the current node de- ployment environment or rules infinite space area, but the actual deployment environment such as battlefields, forest boundary detection and boundary shape is different environments. This paper presents a low - power wireless sensor node deployment scheme of boundary. And the algorithm was named V -HART. On the one hand solution is based on a hexagonal grid configuration strategy to reduce the number of central node; the other hand boundary node program will be placed in the ver- tical line at the two - dimensional hexagonal monitoring area, the number of nodes reducing and lower energy consumption. Simulation results show that, compared to the area of the convex polygon node deployment, V -HART use fewer nodes with low energy consumption, high reliability and using fewer nodes.
