The current era requires high-capacity cellular communication networks of the fifth generation (5G) and beyond (B5G) to meet the increasing demands of global network subscribers. Device-to-device (D2D) technology is an innovative technology utilized in mobile applications, which enables devices such as laptops, embedded devices, and mobile phones to communicate with each other without the necessity of an intermediary network infrastructure. This has benefits in terms of energy consumption, latency reduction, and high communication link throughput. In order to provide high data rates with high-quality signals, low energy consumption, and low latency (packet delay time) services between end users on the networks, D2D is a key enabling technology for 5G and beyond networks (B5G). D2D technology can therefore play a significant role in meeting the ambitious requirements of future 5G and beyond wireless systems, as it primarily relies on infrastructure-centric cellular solutions to meet the demands of services and data traffic. Quality of services (QoS) and energy efficiency (i.e., energy consumption, EE) have emerged as crucial requirements and concerns in the design of 5G technology. We examined the performance parameters for QoS, throughput, energy efficiency, and network latency offered by B5G wireless networks when employing D2D technology in mobile applications. The study focuses on examining both communication and discovery as two D2D phases to fulfill requirements when taking into account the performance indicators for B5G wireless networks that were previously discussed. To show the simulation results, MATLAB has been utilized as a simulator.
