Performance Evaluation of Spectrum Sharing Mechanisms D2D Communication in Next-Generation-Networks

Fifth-generation (5G) technology plays a vital role in enhancing proximity communication such as device-to-device (D2D) and vehicle-to-vehicle (V2V) whereby the closely distant nodes communicate with each other without a need for base station. It helps in increasing the data rate, reducing latency, and increasing bandwidth. It is widely believed that D2D communication, which makes use of existing cellular frequency bands, plays a key role in next-generation wireless technology due to its reliability, low-latency, and the ultra-wide capacity that it provides. This study examines and analyzes the spectrum sharing mechanisms for the D2D communication considering a single-cell scenario. This paper also sheds light on how D2D increasea spectral efficiency by utilizing the macrocel. The findings of this paper demonstrate that the datarate can be improved by about 10 Mbps improved SINR rates, but fluctuating fairness when using the D2D
