The rise in mobile users has increased demand for proximity services with high data rates. A roadmap for dependable and resource-efficient solutions is provided by the fifth generation (5G) of wireless networks, which promises to enhance current technology in accordance with future demands. In order to enable capabilities like live video and data sharing, device-to-device (D2D) communication has been conceptualized as an associated technology of 5G wireless systems. The possibility for device-centric communications utilizing the D2D communication approach is increased by using direct D2D links rather than only cellular links. Offloading traffic from traditional network-centric entities to a D2D network increases network capacity and reduces base station processing. Direct communication between devices improves spectrum efficiency but has drawbacks as well, such as interference. Using the spectrum effectively while reducing the effects of interference could be made possible through intelligent resource allocat
