Optimization of Quality of Service in 5G Cellular Network by Focusing on Interference Management

In recent years the increase of mobile devices and users of the internet has led to an increase in the burden on the network, low connectivity, low bandwidth, and less throughput. With many advantages of the 5G cellular network, this network suffers from signal interference which causes a massive problem for the network. There are many challenges in the cellular network related to energy consumption, and one of the leading and critical issues in 5G is interference management. There is poor voice quality during indoor communication, so interference management provides Quality of Service (QoS) to improve this communication. In indoor communication, there is low power compared to outdoor communication because there are many users, and due to users, there are low data rates and overhead on the base station. From this viewpoint, modulation schema and coding schemes achieve better channel conditions, a significant convergence area, and better QoS. This research proposes a scheme named multiple input multiple output (MIMO) technology for interference management in a 5G network. The evaluation of this scheme with a relay strategy has also been carried out to avoid interference and enhance the strength of the propagated signal. The simulation has revealed the performance of the proposed interference management scheme with a relay strategy based on performance evaluation parameters such as end-to-end delay, throughput, path loss, and energy consumption.
