WSN的GAF算法程序针对无线传感器网络节点部署密集的特点，提出了 GAF 算法。在 GAF

算法中，根据节点的地理位置信息和节点的无线电发射半径（radio range），传

感器网络部署区域被划分为虚拟单元格（virtual gird）。根据自己的物理位置信

息，各个节点被划入到自己的单元格中。各个节点的物理位置信息可以由 GPS 或

其它定位系统得到。

-GAF algorithm of WSN deployment intensive features for wireless sensor network node, proposed GAF ​ ​ algorithm. In GAF algorithm, the radius of the radio transmitting node and the node' s location information (radio range), the sensor network deployment area is divided into a virtual cell (virtual gird). According to their physical location information, each node is classified into its own cell. The physical position information of each node can be obtained by the GPS or other positioning systems.
