一种基于无人机协作的节点数据采集框架

Data collection framework of unmanned aerial vehicle -aided internet of things

为了提高基于无人机采集节点数据的应用场景的数据采集效率,提出基于无人机协作的节点数据采集(DCFU)框架。DCFU框架采用低功耗蓝牙技术传输数据。当无人机进入节点的通信范围,无人机就开始收集节点数据,进而缩短在无人机盘旋在节点上空的时间。DCFU框架建立了上传数据协议和下载数据协议,提高通信效率。同时,DCFU框架采用了线性部署和圆形部署两类节点部署策略,并讨论了这两类部署条件下的无人机遍历的节点数。性能分析表明,相比于同类的框架,提出的DCFU框架的数据采集效率提高了近23%。

In order to improve the efficiency of data collection in application scenario of unmanned aerial vehicle-based collection data of nodes, Data Collection Framework of unmanned aerial vehicle-aided(DCFU) framework is proposed in this paper. In the DCFU framework, the node uses low power bluetooth technology to transmit data. When the drone enters the communication range of the node, it begins to collect data from the node in order to reduce the time of hovering over the node. Moreover, data upload protocol and data download protocol are established. Then the efficiency communication between unmanned aerial vehicle and nodes is improved. At the same time, both of linear deployment and circular deployment is used in DCFU framework, and the number of nodes traversed by unmanned aerial vehicles in linear deployment and circular deployment conditions is discussed.Performance analysis shows that the proposed DCFU framework improves the efficiency of data collection by nearly 23% compared with similar frameworks.
