Modified RQM with Feedback Compensation for Better Congestion Controlled Transmission in Wireless Link

V. Savitha, G. Maria Priscilla

Abstract


Active Queue Management (AQM) is the technique of signaling Transmission Control Protocol (TCP) sources from middle routers with the focus of managing queue utilization and delay. In wireless networks, where the accessible link bandwidth is unreliable with time, it is significant to examine the robustness of the congestion control algorithms against the capacity of disturbance. The main purpose of an RQM mechanism is to offer low delay and low loss service in best-effort service networks. In this work a modified RQM algorithm based on feedback compensation technique is proposed. The algorithm is called Modified Proportional Integral based series compensation, and Position feedback compensation (Modified PIP). The performance of Modified RQM with Feedback (MFPIP) is compared to existing RQM based on the End-to-End delay and bandwidth utilization. From the experiments and analysis it is found that the Modified RQM with Feedback (MFPIP) is more responsive to and robust under time-varying network conditions than existing RQM.
