Title
Performance analysis for the QoS support in LTE and WiFi
Abstract
In recent decades, staggering number of mobile applications have been developed in the wireless technology arena. The Wireless Fidelity (WiFi) and the Long Term Evolution (LTE) have become the most common wireless technologies used for those applications. Mobile applications are classified into Real-Time (RT) and Non Real-Time (NRT). The growth in the number of users burdens the network with more congestion which requires techniques to carry different types of traffic simultaneously in order to alleviate the problem. Different types of traffic (RT or NRT) are managed by Quality of Service (QoS) provisioning techniques. The main issue with the dominant services (RT applications) is the fact that they are delay sensitive, and this is the motivation for building a scheme that enables both LTE and WiFi systems to achieve reasonable values for delay, jitter, and packet loss. In this paper, we propose a QoS provisioning method that could be adopted by both LTE and WiFi, separating the traffic into RT and NRT applications. In the first stage, Class-Based Weighted Fair Queuing (CBWFQ) and Round Robin (RR) disciplines are used for RT and NRT applications respectively. In the second step, Deficit Weighted Round Robin Queuing (DWRRQ) is used for all applications. In this paper, we have analyzed the results of implementation of the proposed scheme in LTE and WiFi networks, and have made a comparison between their results (jitter, end-to-end delay, and traffic received). Simulation results demonstrate improvement in delay for RT in both networks.
