中文摘要：
移动目标跟踪是无线传感器网络中的重要研究课题和研究热点之一。分布式组管理机制是移动目标跟踪系统的核心组件，是系统达到高可扩展性和低能耗的关键。本文提出了一种基于目标射频信号强度的贪婪式组管理机制，从组的构建和组的维护2个方面对其工作机理进行了详细阐述，并针对系统运行时可能出现的各种异常状况给出相应的解决方案。本文最后给出了组管理机制在TinyOS平台上的具体实现，以及在实际中的部署效果和从中获得的经验。
英文摘要：
Mobile target tracking is one of the most important research topics in wireless sensor networks. As the core component of target tracking system, distributed node group management and low power consumption. This paper proposes a dynamic RSSI-based scheme is the key to high system scalability greedy group management scheme and describes the details of its operation principle in terms of group maintenance as well as group formation. The solutions are presented for possible abnormal cases in the system running. In the end, this paper presents the implementation of the group management scheme on TinyOS platform, and the deployment results of the proposed scheme and acquired experiences in practical applications.
