Abstract:

A topology reconstruction method based on one-hop neighbors is proposed to address challenges in unmanned aerial vehicle formation with leader-follower strategy that struggle to maintain formation shape during flight due to communication faults. Before formation flight, the proposed method comprehensively considers the impact of transmission iteration of position errors and the distance factor on communication costs. The communication topology is initialized based on the minimum spanning tree problem, ensuring optimal communication costs while reducing formation errors. In the event of communication topology interruption caused by faults, connectivity is restored through topology reconstruction between local nodes, guaranteeing unmanned aerial vehicles' safety and formation maintenance. Finally, simulation experiments demonstrate the effectiveness of the proposed method. Compared to existing research, the proposed method substitutes global information with local formation details to decrease the number of unmanned aerial vehicles involved in reconstruction, which makes it more adaptable to unmanned aerial vehicle formations of different scales and effectively reduces the computational time and resource consumption in large-scale formation topology reconstruction.

Key words: unmanned aerial vehicle formation, communication fault, topology reconstruction, formation maintenance
