Ad hoc networks are often used in scenarios such as environmental monitoring, reconnaissance reporting, and alarm. In order to realize correct and efficient data transmission of high-load nodes in the network, this paper proposes a node priority-based dynamic TDMA algorithm (NPB-DTDMA), which defines the node priority according to the usage proportion of the node's sending queue and enables the high-load nodes in the network to have advantages in obtaining information time slots. The simulation results show that when packet sending rate is lower than saturated transmission capacity, NPB-DTDMA algorithm can achieve higher throughput, lower packet loss rate, and lower average end-to-end delay than P-TDMA, E-ABROAD, and fixed TDMA algorithms.
