Abstract
This paper proposes a novel dynamic time-division multiple access (TDMA) protocol, which can tolerate stochastic channel interruptions for UAV communication in low-altitude environments. In particular, the proposed protocol dynamically adjusts the allocation of slots by predicting the probability of channel interruption. As a result, this method could improve the utilization of time slots through first guaranteeing the transmission of high-priority services. Simulation results show that compared with the existing dynamic TDMA protocol, the novel slot allocation algorithm based on the channel outage probability reduces the packet loss rate of the service and shortens the average delay of system.
