Abstract: To provide solution to the congestion problems, a single nerve cell adaptive PID control mechanism, which is based on the probability drop scheme of the network node, is proposed and analyzed. Simulation that runs on the OPNET software is carried out on single node traffic model. The simulation results show that the mechanism proposed works well in terms of stability of the average queue size and system robustness.
