Assessing Coverage and Throughput for D2D Communication

In this paper, we access the performance of a Device-to-Device (D2D) communication link. Particularly, we design a framework to evaluate performance with respect to coverage probability and average throughput. Our modeling framework considers a variety of D2D deployment scenarios (i.e., Outdoor-to-Outdoor, Outdoor-to-Indoor, and Indoor-to-Indoor), channel effects (i.e., path loss, shadowing, and small-scale fading), and system parameters (i.e., resource block size, fixed Modulation and Coding Scheme (MCS) versus adaptive MCS, and transmit power). For the defined scenarios, we derive mathematical expressions for the coverage probability and average throughput as a function of the distance between two D2D user equipments. Based on the designed framework, we conduct an extensive performance evaluation of the D2D communication link under various D2D deployment scenarios with varying channel effects. We also evaluate the impact of system parameters, including Physical Resource Block (PRB) size, fixed/adaptive MCS, and transmit power, on the performance of D2D communication links. Our results demonstrate the expected performance that can be achieved in practical D2D scenarios.
