摘要：

In the tactical data link system, the tactical unit may be destroyed at any time to cause the dynamic changes in the network topology, resulting in reduced system service efficiency. In order to solve this problem, an adaptive polling access control protocol (APACP) is proposed based on the idea of dynamically adjusting the polling order. The system is modeled by the probability generating function method and the embedded Markov chain theory to obtain the analytical solution of average queue length and average polling period of system. Then the MATLAB and field programmable gate array (FPGA) are used to verify the protocol in simulation. The simulated results show that the APACP protocol can automatically adjust the polling order according to the dynamic changes of the tactical data link network topology, which significantly reduces the average queue length and average polling period of system, and overcome the empty polling of traditional polling access control protocol, thus saving the service time, improving the service efficiency and improving the system performance. © 2019, Editorial Board of Acta Armamentarii.
