无线传感器网络中，在节点覆盖范围内，形成的拓扑结构图，对学习传感器网络VC++编程有一定益处。

通过随机部署信标节点来定位目标，当距离最近三个信标节点之间相互连接时，出现在信标节点组成的网格内，可以定位目标对象(The target object is located by the random deployment of beacon nodes. When the nearest three beacon nodes are connected to each other, the target object can be located in the grid of the beac
