中文摘要：
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．
英文摘要：
As a result of combination of sensor technology, low power computing and wireless networking, wireless sensor networks is a novel technology about acquiring and processing information. In this paper, the wireless sensor networks and R-tree are briefly introduced. Taking account of the character of wireless sensor networks, we propose a management for sensor node base on R-tree. The management can manage the spatial information of the sensor nodes effectively. Finally, we proposed valid settlements for spatial query and spatial privilege management based on the management.
