Problems solved by technology

During the execution of the mission, the UAV swarm's flying speed is fast and its position is constantly changing, which will lead to frequent updates of the topology of the communication network. If a single node is damaged and leaves the network, it may affect the communication efficiency of the local or global network. With the new single node Join the network to make drone swarm communication network management more complicated

Embodiment Construction

[0048] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0049] According to the characteristics of the UAV swarm system and the constraints of the communication network, a structural model of the UAV swarm communication network is constructed. First of all, the various parameters of UAVs in the initial stage are the same, and there is a two-way symmetrical communication link between UAVs within the communication range. The flight speed of the drone V UAV and direction θ UAV , Communication link quality Q cl , information sending and receiving processing ability C rp and energy dissipation E UAV etc. are important parameters for constructing the UAV swarm communication network structure model. The UAV entities are mapped into nodes, and the communication status between UAVs is mapped into links. Considering the complex and changeable flight environment of UAV swarms, the influence of parameter indicators in d...

Abstract

The invention relates to the technical field of unmanned aerial vehicle cluster communication, in particular to an optimal selection method for a central node of an unmanned aerial vehicle cluster. The method is technically characterized in that a communication network structure model of an unmanned aerial vehicle cluster is constructed, some important parameter indexes are added to accurately select a central node of the unmanned aerial vehicle cluster, and a screening mechanism is adopted to screen and exclude part of unmanned aerial vehicles with extremely low later parameter indexes in advance, a method based on a time window is adopted to realize rapid and efficient selection of dynamic unmanned aerial vehicle cluster center nodes. According to the invention, the unmanned aerial vehicle cluster can have greater communication benefits, the energy consumption of the whole network is further reduced, and the life cycle of the whole cluster communication network can be prolonged.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle cluster communication, in particular to an optimal selection method for central nodes of unmanned aerial vehicle clusters. Background technique [0002] With the rapid development of communication and related technologies, unmanned aerial vehicles (UAVs) have received more and more attention in scientific research and application markets. Because of their continuous enhancement of capabilities and significant improvement in cost performance, UAVs have accelerated their applications in military and civilian fields. The UAV swarm system refers to a system composed of several UAVs with mutual communication capabilities, which integrates intelligent perception, independent decision-making, collaborative control, and performs the same combat mission. In the UAV swarm, each UAV is used as a communication node, and the communication nodes use multi-hops to transmit information to form a c...
