Providing ultra-reliability and low latency of 5G NR traffic

Abstract

The pace of development of telecommunication technologies is increasing every year. More and more devices are using wireless technologies for transmitting information. This increases the pressure on the network, which leads to an increase in the delay in the transmission of data and a decrease in the speed of transmission of information. The development of telecommunications technologies has also affected Internet traffic, as well as the development of the automated industrial production sector (communication with industrial robots, i.e., digitization of production and development of smart factories), the health sector (remote health care), the transport industry (intelligent transport systems, high-speed trains) and the energy sector (intelligent networks). Together, this increases the re-quirements for speed, low delay and reliability of transmission. The evolution of data transmission systems from 4G to 5G is designed to meet the ever-increasing demands of wireless networks. However, one of the current challenges in research on fifth generation networks is the high cost of equipment needed to research new protocols, fine-tune algorithms, optimize network architecture, and organize network topologies. The application of new network solutions is the main obstacle in the study of the radio channel for most lab oratories and research centers. In this regard, the transition from field experiments, which require large economic costs and time resources, to simulation modeling using the NS-3 network simulator is a cost-effective solution in the study of 5G networks. This article presents the features of traffic and the results of modeling the data transmission of ultra-reliable low latency traffic in 5G networks (URLLC) using the NS-3 network simulator.
