The invention provides an information transmission method based on an unmanned aerial vehicle. The method comprises the following steps: when a packet is transmitted between a source node and a destination node using relay transmission of an unmanned aerial vehicle, a transmission model of the packet is established according to the emission energy of the source node, the emission energy of the unmanned aerial vehicle, the flight path of the unmanned aerial vehicle and the transmission time of the packet, the target condition of the transmission model of the packet is that the peak informationage PAoI of the packet is minimum; and the transmission model of the packet is solved by adopting a continuous convex optimization algorithm to obtain a transmission scheme of the packet, and the packet between the source node and the destination node are transmitted based on the transmission scheme of the packet. The method provided by the invention is far superior to a traditional alternating optimization algorithm in the aspects of robustness, iteration speed and the like of the algorithm. By using the algorithm, the minimum PAoI of the device in a specific scene can be quickly obtained, whether information transmission between sensors meets the time delay requirement of a user or not can be conveniently checked, and the algorithm can be effectively applied to the Internet of Things anda 5G scene.
Description
technical field [0001] The invention relates to the technical field of information transmission, in particular to an information collection method based on a drone. Background technique [0002] The continuous innovation and development of science and technology provide a reliable technical guarantee for the development of the Internet of Things. The Internet of Things (Internet of Things) is an information carrier such as the Internet and traditional telecommunication networks, enabling all ordinary objects that can perform independent functions to realize interconnection and intercommunication. The Internet of Things is generally a wireless network, and since the number of devices around each person can reach 1,000 to 5,000, the Internet of Things may contain 500 to 1,000,000 objects. On the Internet of Things, everyone can use electronic tags to connect real objects to the Internet, and their specific locations can be found out on the Internet of Things. Through the Int...
