Abstract

Device-to-Device (D2D) communication constitutes that closely spaced nodes communicate with each other without the use of a centralized base station that carries the communication data. This helps in increasing the data rate, decreasing latency, and expanding the bandwidth and capacity which promotes it to play an important part in next-generation wireless technology. Regardless, the efficient utilization of the available resources is a crucial challenge in D2D systems especially in limited areas; considering that the spectrum is shared across the cell. This paper investigates the spectrum sharing strategies for D2D communication in the context of a single cell by presenting a simulation study of D2D communication performance under different resource allocation scenarios. The first scenario divides the coverage area into inner and outer regions, and the spectrum as well; one for each region, the second scenario assigns resources to nearby users within a range of 10 meters and reuses the resources by other distant users if the separation is more than 50 meters. The variations in the simulation parameters helps to analyze the impact of user location, density, and resource allocation in outdoor urban environments. The simulation results are evaluated in terms of spectrum utilization, and outage probability. These results are analyzed to understand the impact of resource allocation on the performance of the system and thereby show that the second scenario improves the system performance in terms of the outage probability providing useful insights for designing and optimizing D2D communication systems in an outdoor urban environment especially in next-generation-networks.
