Scientists develop droneQQenabled IoT relay for remote environmental monitoring


Unmanned aerial vehicles are poised to take off as powerful tools of scientific research on the roof of the world.

Co-author Zhang Minghu said the research team is exploring ways to apply the system in wildlife monitoring.

The drone-enabled IoT relay system can make up for the network deficiency and will help scientists achieve environmental monitoring in the plateau ster and more easily than before, according to researchers.

The system was developed by the Institute of Tibetan Plateau Research under the Chinese Academy of Sciences. It mainly consists of drone-based relay equipment for data collection and IoT terminals on the ground, including devices for environmental monitoring and data transmission.

In many areas lacking network coverage, data have to be collected manually, said Li, adding that data collection on the plateau is time-consuming and costly.

Chinese scientists have used a drone-enabled Internet of Things (IoT) relay system to achieve real-time environmental monitoring in remote areas where mobile networks are insufficient.


Due to the remote and harsh environment, data sampling on the Qinghai-Tibet Plateau has been infrequent for a long time. Chinese scientists have stepped up research efforts in the area in recent years, but current equipment and poor network coverage are unable to meet the growing research demand.

According to an online article published by the journal IEEE Internet of Things, scientists have carried out several experimental flights in northwest Chinas Gansu Province, which showed the high feasibility of the system.

Scientists used the drones as mobile relays to grab real-time data from monitoring devices deployed in hard-to-reach areas. After that, they flew the drones to areas with broader network coverage and forwarded data to scientific data centers, lead researcher Li Xin told Xinhua Thursday.

Using the drone system to replace the manual observation of wildlife will be much safer, especially with large animals, Zhang said.
