Simulation Studies on 5G Network Performance

Abstract

Within a short period of time, wireless communications technologies have developed to the fifth-generation (5G) network, which is offered with ultra-high data rates, great connections among devices, and low latency. Simulation-based research is crucial towards the study and optimization of the 5G performance under diverse deployment conditions to achieve such ambitious goals. The present paper reviews some of the important simulation studies which analyze the performance of 5G networks in terms of throughput, latency, spectrum allocation, and energy consumption. Different simulation models like NS-3, MATLAB and OMNeT++ are considered in terms of their capacity to model the dynamics of physical layer, mobility patterns and strategies of resource allocation. The results have shown that the use of simulation settings can successfully forecast the actual performance and optimize the network prior to the implementation at a large scale. Nevertheless, there are still challenges of computational complexity, model channel precision, and heterogeneous networks integration. The paper finds that simulation studies are essential to create an efficient 5G architecture, test new protocols, and guarantee that future networks can be used to address the needs of new systems like autonomous, IoT, and immersive communication technology.
