The unmanned aerial vehicle (UAV) Internet of Things (IoT), is an emerging topic in sensing and communication area, which is widely used in 5G mobile communication networks. Compared with traditional static IoT, UAV sensing nodes have the advantages of strong mobility and wide communication service scopes. However, as the scale of 5G networks continues to expand, a single UAV is limited by its energy and wireless transmission capabilities. It is quite challenging to ensure the real-time and reliability of sensing tasks.
The research group takes the lead in proposing the theory and method of UAV cooperative sensing and transmission, where UAVs cooperate with other UAVs, mobile users and ground base stations. It breaks through the limitations of a single UAV's energy and transmission range, improves the real-time and reliability of sensing tasks, and provides theoretical and technical support for promoting the development of 5G UAV IoT.

The research team jointly optimizes the trajectory and speed of UAVs and to manage the communication resources and real-time data processing. A cooperative sensing and communication protocol (as shown in Fig. 2) is designed to support multi-modes communication and sensing tasks of UAVs. The research involves UAV trajectory optimization, communication protocol design, and sensing data transmission and processing. It integrates knowledge from multiple disciplines such as wireless communication, signal processing, and sensing technology. The control theory, the optimization theory, and other theoretical methods are combined to form a set of interdisciplinary research methods, which has guiding significance for the deployment of UAVs in realistic IoT scenarios.
