Connectivity of multiple unmanned aerial vehicles (UAVs) is crucial for distributed and coordinated control. However, due to limited communication ranges and inherent communication delays, traditional connectivity preservation methods often fail to ensure stable network connectivity in delay-prone environments. To address this challenge, we propose a multiple UAVs connectivity preservation controller designed to operate effectively under communication delays.

2. Literature Review 2.1. Method of Traffic Volume Estimation In traffic volume estimation research, methods can generally be divided into two main categories: model-based estimation methods and data-based estimation methods. Each of these approaches has its own advantages and is suitable for different conditions. Model-based estimation methods typically rely on the physical theories and mathematical models of traffic flow.
