Quality of Service based Active Queue Management for Reliable Packet Transmission in Wireless Network

Abstract

Active Queue Management (AQM) is used for TCP networks congestion control. AQM is used to keep away from congestion and to reduce the packet loss in wireless network. Besides, Quality of service (QoS) is extremely poor while congestion occurs in wireless network with active Quality management. The congestion collapses with problems such as throughput for reliable communication, queue delay and packet loss. In order to overcome such limitations, Relative Active Fair Queue Managing (RAFQM) technique is developed in this paper to achieve the AQM with QoS. The main goal of RAFQM technique is to transfer the packets without any loss of information and to enhance active queue manage system for QoS fairness. The Fairness among the QoS metric is achieved in RAFQM technique with the minimal latency and delay. Initially, RAFQM technique is uses the Prime Jitter Packet First concept (PJPF) to easily reduce the delay and to provide effective QoS jitter result. By using PJPF concept, RAFQM technique is reduces the jitter count in the linear and bilinear route paths and also congestion is removed from the active queue managing network. After that, RAFQM technique is used Latency Aware Active Queue concept to reduce the latency time while transferring the packet from the sender to receiver side through the intermediate paths. The Latency Aware Active Queue concept controls the packet flow rate based on the queue size and therefore provides the reliable network communication for packet transmission. Experimental evaluation of RAFQM technique is done with the performance metrics such as packet loss rate, latency time, delay, throughput and congestion control rate. Experimental analysis shows that the RAFQM technique is able to improve the throughput rate by 8% and reduce the delay by 42% when compared to the state-of-the-art works.
