The fifth-generation (5G) and sixth-generation networks will be the bigrevolution in the area of mobile and wireless communication.This will be due to the high data rate and connecting applications in various areas ultralow, the Internetof things (IoT), and massive device-to-device communications.These applications are only possible in the changes of the core network ofthe 5G and 6G virtualizationtechniques with higher performance, low latency,and quality of service guarantee.Due to its potential for multi-gigabit and low latency wireless links, millimeter wave (mmWave) technology is expected to play a central role in 5th generation (5G) cellular systems. The growing demand for ubiquitous mobile data servicesalong with the scarcity of spectrum in the sub-6 GHz bandshas given rise to the recent interest in developing wireless systems that can exploit a large amount of spectrum availablein the millimeter-wave (mmWave) frequency range. Overcoming the poorradio propagation and sensitivity to blockages at higher frequenciespresents major challenges, which is why much of thecurrent research is focused on the physical layer. In this paper, the mmWave module is integrated with ns–3 simulators to incorporate real measurements or raytracing of data and simulations of end-to-end connectivity and dual-connectivity. This paper also presents an open-source framework to model the mmWave cellular networks using an ns-3 simulator with a configurable physicaland MAC-layer implementation, that may be communicated with the higher-layer protocols and core network model to simulate end-to-end connectivity.Our framework may help to simulate the various situations to enhance the end-to-end performance of the 5G cellular network using the mmWavemodule.
