Nodes in the communication network mainly depend on the Media Access Control (MAC) layer protocol design. To ensure the MAC protocol achieves high throughput, low latency, and high service quality, this paper designed a “centralized-distribution” system MAC protocol combined with a slot allocation algorithm. This allows it to quickly adapt to the topology changes in the network and the overall network frame structure. For the centralized time slot allocation, since the system’s frame structure changes across the entire network, the root node must gather information from other nodes. This ensures that the root node can collect the latest topology information when the network topology changes and subsequently adjust the frame structure of the whole network for the distributed time slot allocation. The simulation results show that the adaptive time-division multiple access mechanism can quickly adapt to changes in topology and the network’s frame structure. It enables adaptive changes in node transmission times, ensures the rapid transmission and circulation of large-capacity data between nodes, and improves transmission efficiency.
