Performance Evaluation of Scheduling Algorithms of LTE and LTE-A Mobile Networks using Vienna Simulator

Abstract

The third-generation partnership architecture specifies Long Term Evolution to give high data speeds of up to 100 Mbit/s and 50 Mbit/s for downlink and uplink transmission, respectively. It can be employed in a variety of bandwidth bands from 1.4 MHz to 20 MHz .The Vienna LTE simulator was used to examine the performance of homogeneous and heterogeneous networks by changing the various physical parameters. There are several distinct qualities that are employed, including through-put, spectrum efficiency, and fairness index. The scheduling mechanism is the process of allocating resources (time and frequency) to users who are simultaneously transmitting different streams. Several scheduling strategies, such as Round Robin, Proportional Fair, and Best CQI, are being looked into. Fractional Frequency Reuse (FFR) is also used to improve performance and reduce edge user disruption. Additionally, eNodeB and femtocells are included in the heterogeneous network, which is easily compared to the homogeneous network.
