摘要
传感器节点的部署是无线传感器网络研究的一个重要分支。证明了传感器节点覆盖圆盘与其邻居节点覆盖圆盘的交点构成正六边形蜂窝时,有效覆盖面积最大;提出了一种基于蜂窝网格的传感器节点部署算法,通过仿真与已有的基于方形网格的部署算法进行比较,结果证明:本算法能更有效地控制成本。
Sensor nodes placing is an important branch of WSNs research. The cover circle sensor node intersects with other circles of all its adjacent nodes, and when the points of the intersection compose a hexagon, the effective coverage area of the sensor node gets its largest. A sensor node deployment algorithm for the honeycomb grid is put forward, and the result testifies its efficiency in cost control by simulation and comparison with current deployment algorithm for the rectangle gird.
