With the rapid development of unmanned swarm combat systems, large-scale Unmanned Aerial Vehicle (UAV) swarm networking have become a hot topic of research. In response to the current gaps in the research of large-scale UAV swarm networking architecture, such as network rapid construction and network reconfiguration, a networking architecture suitable for large-scale UAV swarm networking has been designed. The network architecture can support various combat missions such as UAV formation flight, coordinated reconnaissance, and coordinated attack. It uses fewer initial parameters to flexibly and quickly construct the network, and can adaptively reconfigure the network when important nodes are damaged. Through the OMNeT++ network simulation software, node models and system operation models are established to simulate the rapid construction of the network, cluster head distributed bootstrapping, and conflict elimination protocol for large-scale UAV swarm networking. The rapid construction and network reconfiguration capabilities of large-scale UAV swarm networking are verified.
