| Abstract: | Aiming to solve the problem of low communication reliability in emergency scenarios, we propose a power control policy for device-to-unmanned aerial vehicle communication based on automatic repeat request. Through representing the communication reliability to the communication failure probability, this paper first analyzes the failure probability of receiving packets and ACKnowledgement (ACK) to obtain the D2U communication failure probability; and then formulates the optimization problem of communication failure probability under the fast fading and slow fading model, respectively. To address the optimization problems, we design an iteration-based power control algorithm. The algorithm fully considers the energy consumption caused by retransmissions and the loss of ACK. Monte Carlo simulation results show that the power control policy proposed in this paper has a lower communication failure probability compared with others, thereby ensuring the reliability of D2U communication in emergency scenarios.
