In recent years, more and more applications use ad-hoc networks for local area communications, especially in key technologies that are expected to play a vital role in future society, and HANETs (Heterogeneous Ad-hoc Networks) are becoming a hot topic. In this study, we propose a connection stabilization method for HANETs composed of drone swarms, assuming 1) every drone moves independently without being aware of inter-connectivity and 2) only protocol translators, which called GWs, are controllable for their movement. Proposed method consists of two algorithms; neighbor clustering algorithm based on relative speed and mobility control algorithm based on kinetic model. We carried out computer simulation to evaluate the performance and it turned out the method achieves significant stability improvements under some parameter conditions. We also discuss specific application scenarios of proposed method considering its performance characteristics.
