The clustering algorithm of UAV Networking in Near-space

Considering the features of UAV (unmanned air vehicle) networking in near-space, such as low network performance, ineffective communication capability of UAV clusters and the difficulty to manage UAV while it is out of sight, this paper proposes a space-Earth-based integrated - "Calculate on the ground, Adjust in the space" thought to design a "clustering algorithm of UAV networking in near-space". The mathematical analysis and simulation results show that this algorithm can effectively improve the stability and flexibility of near-space clusters, economize the systematic expense, guarantee the movable networking ability of nodes in the space by reducing the calculation of nodes, and realize the clustering and networking of nodes in near-space environment the ability of which is limited.
