Modeling Optimal Values of the Traffic Load-Based Factors over Performance of LTE Cellular and 802.11ac

Abstract

The load-based features of the traffic particularly in resource-limited wireless systems, including LTE and 802.11ac, are among the primary factors that any changes in their values can directly affect the efficiency of the networks. Keeping in mind the fact that proper selection of the parameters is very crucial for performance optimisation of the networks, this work proposes a comprehensive framework called loadbased factors (LBF) with two main purposes. First, to quantify and determine the effects of the load- based parameters including traffic source rate, traffic type, and packet size on the performance of LTE and 802.11ac networks. Second, to accurately determine the actual effective values of these parameters and achieve the performance optimality in both LTE and 802.11ac networks. The NS3 tool is used to implement and evaluate the LBF framework. The experimental results show that the proposed framework by varying these parameters and testing the corresponding impacts via implementing a wide range of scenarios and experiments can be used as a comprehensive model to determine and compare the optimal values of these parameters in both LTE and 802.11ac networks.
