“…Examples of heuristic schemes are RED [6], gentle RED (GRED) [11], adaptive RED (ARED) [12], parabola RED [13], hyperbola RED (HRED) [14], dynamic RED [15], flow RED [16], stabilized RED [17], balanced RED [18], BLUE [19], Yellow [20] etc. These algorithms aimed to improve some or all of the features, such as fairness, stability, network utilization, packet loss and adaptability for different traffic loads.…”

Abstract:With the advancement of the Long-Term Evolution (LTE) network and smart-phones, most of today's internet content is delivered via cellular links. Due to the nature of wireless signal propagation, the capacity of the last hop link can vary within a short period of time. Unfortunately, Transmission Control Protocol (TCP) does not perform well in such scenarios, potentially leading to poor Quality of Service (QoS) (e.g., end-to-end throughput and delay) for the end user. In this work, we have studied the effect of Active Queue Management (AQM) based congestion control and intra LTE handover on the performance of different Medium Access Control (MAC) schedulers with TCP traffic by ns3 simulation. A proper AQM design in the Radio Link Control (RLC) buffer of eNB in the LTE network leads to the avoidance of forced drops and link under-utilization along with robustness to a variety of network traffic-loads. We first demonstrate that the original Random Early Detection (RED) linear dropping function cannot cope well with different traffic-load scenarios. Then, we establish a heuristic approach in which different non-linear functions are proposed with one parameter free to define. In our simulations, we demonstrate that the performance of different schedulers can be enhanced via proper dropping function.

Abstract-It has been observed that a bottleneck Random Early Detection (RED) gateway becomes oscillatory when regulating a flow in multiple TCP connections. The stability boundary of the TCP-RED system depends on various network parameters, making the adjustment of the RED gateway a difficult task. Based on a fluid-flow model, we formulate analytical conditions that describe the stable boundary of the RED gateway depending on the number of TCP Reno connections. The proposed model accurately generates a stability boundary surface in a four dimensional space, which facilitates the adjustment of parameters for stable operation of the RED gateway. The accuracy of the analytical results has been verified using the ns-2 network simulations.

“…This model represents the behavior of the characteristic variables of the network and shows that it accurately captured the qualitative evolution of TCP traffic flows. Based on this model, a lot of research [3]- [5] and [6] has been done to find the proper tuning parameters of RED. The key requirement in selecting the appropriate parameters is the stability of TCP/RED systems.…”

Abstract-Active Queue Management (AQM) is a key congestion control mechanism for reducing the packet loss and improving the network utilization in TCP/IP networks. This paper discusses previously developed PI controller for AQM and proposed a new GA-based PI-PD controller. It is able to control present congestion reactively and also avoid the incipient congestion proactively. Fast response to the changing traffic is achieved by PD to maintain a desired queue length, high link utilization and low packet loss. The optimized tuning parameters are determined by selection of an Integral Square Time Error (ISTE) as an objective/fitness function. We use ns simulation to demonstrate the practical advantage of using GA-based PI-PD controller over PI in managing constant queue length.Index Terms-Congestion control, genetic algorithm (GA), integral square time error (ISTE), transmission control protocol (TCP).
