specific Embodiment 1

[0068] The validity of the present invention is verified. Assuming that there are 6 UAVs in the self-organizing network, during the operation, the central node is randomly closed to simulate the damage or loss of the central node. Consider the following two cases to evaluate the performance of the method of the present invention:

[0069] 1) The self-organizing network is connected normally, and information can be exchanged between the 6 UAV nodes normally;

[0070] 2) The connection of the self-organizing network is interrupted, and it is divided into two connected sub-networks, each of which contains three UAV nodes (note: the algorithm is not limited to this specific case).

[0071] Figure 5 The state transition process of 6 UAVs is represented, in which 0, 1 and 2 represent the nodes Leader, Candidate and Follower respectively. Figure 5 (a) means: if the network is connected normally, only one leader is active in the whole process; when the leader disappears or crashe...

Abstract

A distributed center selection and communication method for unmanned aerial vehicle swarms belongs to the technical field of unmanned aerial vehicles, and is used to solve the problem of the collapse of the unmanned aerial vehicle swarm communication network caused by the disconnection of the central node in the existing centralized communication network. The technical gist of the present invention includes: describing the UAV node state as one of the following three: Leader, Follower and Candidate, by dynamically adjusting the node state to cope with the complex network environment, taking into account possible problems in the node state transition Various situations, and given the countermeasures, when the Leader does not exist or is disconnected in the communication network, the UAV fleet can quickly, autonomously and distributedly select a new Leader as the central node, so as to establish a new centralized communication network. The invention ensures the global optimality of the back-end global situation awareness and decision-making, and at the same time solves the problem that the centralized communication architecture is not robust in the confrontation environment. The invention can be used in task distribution of unmanned aerial vehicle clusters.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle communication, in particular to a distributed center selection and communication method of an unmanned aerial vehicle swarm. Background technique [0002] In recent years, the development of precise navigation technology and 5G communication technology has made the swarm application of UAVs more and more common. The improvement of self-organization ability and intelligence makes it widely used in various tasks, such as fire detection, cooperative search and cooperative interception. To complete the task autonomously by the UAV fleet, it is necessary to establish a stable and reliable UAV fleet communication network to transmit the information of individual UAVs, form situational awareness of the current working environment, and coordinate the UAVs to perform corresponding tasks. [0003] There are two main types of communication network architectures for UAV swarms: centralized an...
