Simulation of a Prototype 5G Network Integrating D2D Communication and MEC Technology

In this paper, we study the coexistence of two key technologies in the same fifth-generation network, namely D2D (Device-to-Device) communication and MEC (Multi-Access Edge Computing) technology. These two promising technologies each have important roles to play in future telecommunications networks. D2D communication is a technology that aims to improve communication efficiency, increase overall throughput, and decrease latency. Multi-Access Edge Computing, a promising new concept, overcomes the burden of core cloud servers. This makes it possible to provide large storage, compute, and resource capacities to mobile edge nodes. With its closest deployment to users, it significantly reduces end-to-end transmission time. Our architecture consists of an access network and a central network, a base station (gNodeB), users, an MEC server and a gateway (UPF) to connect it to the RAN (Radio Access Network) of the core network. The base station controls communication by managing signaling and interference. The MEC server is placed next to the BS to provide data to the devices. It plays the role of the cloud that is located in the core network and allows you to store data and then do calculations for good communication between devices. Finally, we did a simulation using the OMNeT software. The results showed us that the data transmission passed well between the end devices, the antennas and the MEC server with very low latency and reliability.
