The congestion is the most important issue that effects on the performance
of data transition over internet networks. One of the important techniques
developed is active queue management (AQM) that prepares an efficient
congestion control by reducing losing packets, queue size, and energy
consumption. Therefore, AQM technique deemed as a base of many
congestion control algorithms schemes. This work suggested the using of
proportional integral (PI) controller as an AQM and then use an optimized
control system such as biogeography-based optimization (BBO) with PI
controller as (BBO-PI). The optimal control (BBO-PI) is characterized by
access to design and fine-tuning of defining the shapes of the optimal
parameters of PI controller. The BBO algorithm was implemented by using
the mathematical system model by M-file/Matlab and Simulink.
The simulation results showed the best performance for the transmission
control protocol (TCP) network when compared the system with using the PI
controller and using optimal control (BBO-PI), the ratio of enhancing the
system with using of BBO-PI better than using a PI controller only in terms
of rising time is 1.11, settling time is 2.85 and overshooting is 85%.
Therefore, the proposed method was very fast and required few iterations.
