基于ZigBee的空中网关自组网机制设计

Design of Air Gateway Self-organized Network System Based on ZigBee

野外远距离分布式无线传感器节点依靠传统的单跳难以实现可靠的数据传输。提出基于ZigBee的动态自组网模式,采用无人机搭载空中协调器网关,实现唤醒并组网获得数据。协调器将收集到的数据打包传到WiFi模块,Android端App可以实时查看。实验结果表明,该系统可以完成对远距离分布式传感器的数据采集,并延长了野外节点的生存寿命。

As it’s difficult for the sensors which are distributed in the wild or far from the monitoring area to achieve reliable dattransmission in traditional signal-hop data transfer. A ZigBee-based self-organized network is proposed and UAV is used to carry the aigateway which will wakes system up and organizes a network to receive the data. Coordinator will package the data it collects to the WiFmodule. The data can be checked at any time by the Android applications. Test results show that this system completes the sensomonitoring from far distance,and extends the life of nodes in the wild.
