With recent improvements, emergence and service dependency of smart communication devices, there has been increasing demand for better quality of service (QoS) provisioning and experience (QoE) implementation at low operational cost. Wireless networks experience some uncertainties which results from the unpredictable nature of wireless signals, interferences and signal propagation, leading to overall degradation of the entire system. The results lead to packet loss, fading, delays, reduced throughput and low latency. This paper is aimed at using PID Control Techniques to track network uncertainties in a TCP-based network and at the same time cancels it to enhance the overall system performances. System performance measurement and analysis of the TCP- based network was performed with a link capacity of 3750, 4200 and 4500 packet/seconds respectively in three scenarios. The results showed that the PID control technique recorded a sensitivity value of 0.0329dB, 0.0345dB and 0.0821dB. (all are less than 1dB), this means that it achieved good sensitivity level to network disturbance for faster disturbance rejection capability and reduced sensitivity. The results also shows improved delay reduction, reduced throughput, low latency, packet loss and mitigate fading issues. The PID control technique was recommended for wireless network improvement to attain enhanced performance, stability and good QoS.
