With the constant development of Internet,the possibility of severe Internet congestion collapse receives much more concern.Efficient congestion control mechanism is one of the key elements to the stability of Internet.To solve the congestion problems,a PID control mechanism based on single nerve cell self-adaptive control algorithm is proposed and analyzed.Simulation that runs on the OPNET software is carried out on multilevel node traffic model.Simulation results show that the proposed mechanism works well in terms of stability of the all levels queue size and system robustness.
