Aiming at the problem of time slot resource allocation in tactical data link network, combining FPRP algorithm and P-TDMA algorithm, the exponential incremental exponential decrease (EEED) backoff algorithm is introduced, and the competition access probability is improved, propose a dynamic time slot allocation algorithm TDMA based on Adaptable Probability Contention (APC-TDMA). The algorithm collects two hop adjacent node information through multiple exchange information, and performs time slot allocation in two hop adjacent nodes, realizes the time slot space division multiplexing outside two hops, and solves the problem of node hiding and node exposure. The algorithm is simulated and analyzed using OPNET software. The simulation results show that the algorithm performs well in the end delay, network throughput and time slot utilization in large-scale network environment, and can meet the requirement of battlefield actual information transmission.
