Performance Evaluation of LTE And WiMAX Throughput Networks

Abstract:

The Long Term Evolution (LTE) and worldwide Interoperability for Microwave Access (WiMAX) Technologies offer a long term solution to the Broadband wireless communication in the last decade. Each type of application needs a certain level of service commitment from LTE and WiMAX Networks in order to operate successfully. There are a number of factors and components, which affect the Network performance, this leads to a requirement of Quality of Service (QoS) in the LTE and WiMAX Network. In this paper the Performance Evaluation of LTE and WiMAX Throughput Networks was introduced to improve the performance for both LTE and WiMAX Network. The propose model was simulated and evaluated in the OPNET modeller 16.0 using multiple Access Points (APs), Base Stations (BSs), Subscriber Stations (SSs), and some selected server BSs selected using a designed Nearest Neighbourhood Algorithm. The propped Distributed Client Server model used Orthogonal Frequency Division Multiplexing (OFDM) techniques while the Existing Centralised model used Frequency Division Multiplexing (FDM). The results obtained from the simulation shows significant improvement in the LTE Throughput Network as compared to WiMAX Network Throughput this shows that the model's results imply the LTE network's throughput significantly outperforms the WiMAX network.
