集成了计算、通信和传感器这三项技术的无线传感器网络是一种全新的信息获取和处理技术.在简单介绍传感器网络和R树相关知识的基础上,针对传感器网络的特点提出一种基于R树的传感器节点管理方法.该方法可以把传感器网络中节点的空间信息有效地管理起来,进而扩充传感器网络的功能.最后,基于这种管理方法分别给出空间区域查询和空间权限管理的解决方法.
Based on the knowledge of sensor networks and R-tree, this paper proposes a new wireless sensor network based on the three technologies of computing, communication and sensor, which is a new information acquisition and processing technology.Aiming at the characteristics of sensor networks, This method can effectively manage the spatial information of nodes in the sensor network and further expand the function of the sensor network.Finally, based on this management method, we give the solution to the spatial domain query and the spatial rights management .
