Demonstration of an Effective 4G LTE Network Simulator to Analyze Performance and Ensure Reliable Communication
Abstract
With the growing population, technology is growing without any bounds. With these advancements, we have reached a footing where we cannot imagine the world without communications. This dependability on communications strikes a need for highly reliable and cost effective communication technology from the perspective of the user as well as the service provider. Though the 3GPP’s Long Term Evolution (LTE) has been successful to mitigate most of the challenges, there arises a need to foresee the cellular network evolution considering various factors like increase in number of users in a particular area, urbanization etc., and accordingly use the features of LTE to overcome the effects of them before actually deploying the network in the real world. This thesis outlines the requirement for an effective 4G LTE simulator that can model the real world cellular network by considering the various effects on a wireless network like fading, pathloss, number of users and resource allocation. It can then explore various aspects of 4G LTE that contributes towards design and analysis of the network performance for various
scenarios supporting deployment of the new network for futuristic operation or optimizing the existing network. In this study we closely look through a System level LTE Simulator developed by the Institute of Telecommunications of The Vienna University of Technology, Austria. Using this simulator we study different scheduling schemes to evaluate performance and demonstrate how important the role of scheduling scheme is to overcome network congestion. We study various features of LTE that help in increasing throughput for various traffic models over a network and demonstrate the role of small cells in increasing the overall throughput of the network by comparing with the existing macro cell network.
Various parameters are varied and results are obtained for various scenarios using the Vienna LTE simulator. These results are then used to demonstrate how Quality of Service (QoS), capacity planning, and resource management are achieved through LTE technology. This study helps the service provider to offer reliable service at lower implementation cost and deploy a network that has ability to sustain the evolution.
