网络拓扑的研究是未来WSN发展的方向和目标。本文通过对无线传感网zigbee协议、节点组网及网络拓扑等内容的研究，运用无线传感网协调器节点组网并且作为嵌入式网关与上位机PC进行串口通信，实现拓扑结构的GUI显示。本文设计实现了一种节点网络拓扑可视化的方法，用图形描述节点之间抽象的拓扑结构，对网络的稳定性和多跳性进行研究。同时，本文对节点设备的温度、节点电压、RSSI的采集，实现网络中节点状态实时监测以及网络寿命的评定，对于研究高效、稳定的网络拓扑结构有着重要的意义。

The research of network topology is the direction and goals of WSN development. In this paper, based on the study of the content on the protocol of zigbee, wireless sensor node network and network topology, wireless sensor network is set up by coordinator node, which is also built as a the embedded gateway communicating with host computer PC in the USART. Then, a topology GUI is displayed. The network topology visualization with the graphic description about abstract node topology is designed in this paper, the stability of the network and multi-hop is researched in intuition. Meanwhile, the node device temperature and battery voltage are collected to achieve a real-time monitoring of network node status as well as the assessment of the network life, and it plays an signiifcance role for the study of highly efifcient, stable network topology.
