Wireless ultraviolet light cooperative unmanned aerial vehicle secret dynamic clustering system and method

Abstract

The invention relates to a wireless ultraviolet light cooperative unmanned aerial vehicle secret dynamic clustering system and a method. The method comprises the steps that: an ultraviolet light spherical LED array is carried on each unmanned aerial vehicle body, multi-task unmanned aerial vehicles are randomly distributed in a specified space initially, virtual grids are divided preliminarily through the relationship between the total bandwidth and carrier waves, and a virtual cluster head is selected from each virtual grid; the virtual cluster head fuses state information of wing planes in each grid and transmits the state information to an unmanned aerial vehicle base station, the unmanned aerial vehicle base station masters global information and transmits a control instruction to eachwing plane through the cluster head, and each wing plane realizes position state updating according to the control instruction; then an optimized secondary soft threshold is introduced to improve a cluster head selection stage, information transmission of the whole network is completed, and load consumption of communication is reduced; and the control instruction serves as feedback information totrigger a wing plane motion system, and a dynamic network is converted into a relative static network to adapt to an improved LEACH algorithm. According to the method, the clustering problem of the unmanned aerial vehicle dynamic network is solved, so that unmanned aerial vehicle communication energy balance is realized.

Description

technical field [0001] The invention belongs to the field of unmanned aerial vehicle (UAV) network communication, and in particular relates to a system and method for stealthy dynamic clustering of wireless ultraviolet cooperative unmanned aerial vehicles. Background technique [0002] UAV networking is a dynamic real-time network, and real-time and reliable communication between UAVs is especially important. In the ever-changing battlefield environment, when UAVs perform various military tasks, such as surveillance, defense, and strike missions, they will face threats such as radio silence, radio monitoring, and electronic countermeasures, which lead to the communication security between UAVs becoming increasingly difficult. Strict, so the introduction of ultraviolet covert communication method, the ultraviolet spherical LED array is mounted on the body of the drone, and the information is loaded to the ultraviolet light source through modulation to realize information tran...
